windows thinks...

Try uninstalling all the drivers and try one again using x64 (I know you probably did it already, but just confirming).
Maybe try doing a factory reset?

So i uninstalled the drivers using the uninstaller application that came with the download then i deleted the files off the computer.
went to the captivate wiki on xda, downloaded the 64 bit drivers from that link (look exactly the same as the other links), then ran the installer application from that download.
what happened was at the end of the install wizard it said that: "mss install wizard was not completed... install wizard was not succesfully installed samsung usb driver for mobile phones.".
I did however notice that at one point in the wizad it called the driver x86 instea of x64.
i would be lieing if i didnt say i hated samsung right now. o yea and i think at&t too. ha ha
Thanks for the help! : )

so in addition to hours spent on other days, im about 5 hours into trying to make the phone connect today.
it seems worse now, it only sometimes sees a device it cant recognize.
i tried more batches of driver uninstall/installs and i even downloaded the full kies.
nothing seems to make it go. im about to lob this thing across the room. any other suggestions or people with a similar problem?
any help would be much appreciated.

1) Scrub your system again of all Samsung drivers.
2) Go to Samsung Software & Firmware Downloads and get the Mini Kies program.
3) Install Mini Kies, this will install drivers.
4) Set USB settings on phone to ask on connection, Settings>Applications>USB Settings>Ask on Connection
5) Connect phone to computer
6) Select Mass Storage when the phone asks
7) Mount phone to computer, depends on which ROM you are running
8) Report back,
I'm running Windows 7 x64 Home Premium and have no troubles connecting. Hope this helps.

ok thanks for the tips.
Here's what i did:
Download mini kies from the link (i noticed that there were driver there to but i did not download that link)
Set phone to ask on connection
plug phone into computer
set to mass storage.
mount sd card
computer says "usb device not recognzed"
Mini Kies still says "please connect mobile phone"
i scream!
what do you suggest i do from here?

Have you tried a rear USB port instead of a front? I don't know why but many have claimed this was the trick. It should not work, but for some reason it does for some.

The usb ports on the back of the computer are usually connected directly to the motherboard. The usb ports located other places on the computer are usually connected to the mother board via a secondary card of some type - this adds another level of hardware and software drivers required to make those ports work. Also it is not unusual for some usb to operate at different power levels - often referred to as powered and non powered ports.
So not all ports are the same which is why some people have different results on different ports on their computer.

One other option that sometimes works: turn on usb debugging in settings/applications/development. Then connect the usb. Pull down the notification window and select the button that says something like "select to copy files...". This brings up a dialogue box asking to mount the phone, and you select that.

alright i tried
every single usb port (it a laptop btw sorry should of said that earlier)
and also with and without debugging
computer still says usb device not recognized.
is there any more info that anyone needs? Tried hooking the phone up to a mac also (snow leopard osx laptop) no luck still.

I have built many machines and never had a device work on one USB port and not on another.
All my USB devices that require power, require an actual AC adapter -As for unpowered ports - never heard of that. Powered and unpowered hubs yes - but not unpowered ports.

First, just to make this clear all usb ports are powered, and so long as they are in compliance with the usb standard they are powered to 5v.
Second, what you referring to with powered/non powered usb hubs is a usb hub that has a secondary power source (ie includes ac power cable maybe) vs a usb hub that is only powered by the usb serial bus via the usb connecter to the computer.
What was referring to in powered/non powered usb port is a technology included in some ports that allows that port to use the power of two usb ports in one port - not sure but I believe it is an ibm technology - which is some times referred to slangly and inaccurately as powered usb
Now the point of my post was to point out even though there is a universal standard for usb - depending on how these ports are actually connected to the serial bus on the mother board will affect they way they perform - ie usb on the back of the computer that is mounted directly to the mother board serial bus vs one connected via a pci card.
And even though you have never experienced differing performance in your usb ports does not mean that it doesn't happen - it is actually quite common particularly with devices that both connect via usb as well as charge its battery via usb.
I currently have a computer with 7 usb ports all of which will connect and work with my wife's ipod - but I have found two of these ports that will not charge her ipod. most likely this failure to charge her ipod is due to the hardware (or the software driver for the said hardware) in between these two ports and the mother board.
In all of the computers you have built have you built any that had usb ports mounted directly on the mother board serial bus that you also connected a usb pci card to allow for more usb ports? I guarantee you if you do this often enough you wil eventually build a computer that has usb ports with differing performance.

while the info on usb is nice : ) i would very much appreciate any help on gettingmy phone connected. thanks!

I'm guessing by now you have tried all your ports, lol. have you tested your phone on other computers and/or with other usb cables?
One thing to try is check and see if there are any driver updates for the usb hardware in your computer. You can usually find these updates with the computer vendor and/or mother board manufacturer support.

Sorry I missed your post earlier about connecting to a mac - when you connected to the mac was your phone in debugging mode?
I don't know if it is necessary to connect to a mac, but to get some linux distros to mount the drives in cappi it has to be in debugging mode and while linux and NEXTstep are different they are in the same family, have the same ancestor. maybe if someone with a mac read s this they can let us know if it is needed.
If you keep connecting to different computer with no luck, try a different usb cable.

Actually its connecting to a pc. I just tried to connect to a mac wouldn't work there either.
But I've tried all the different combos of debugging and mass storage options it just says it doesn't recognize the usb device.
I have tried a bunch of different drivers and using both kies and mini kies.

Captivate (stock everything)

getting unrecognized usb device is almost certainly a driver issue - what ever kept it from working with the mac is something else.
have you downloaded and installed the drivers dg has linked in his odin 3 one click thread?
Second have you had a chance to check if your computer had any usb driver updates? One of my machines would not properly identify my phone that I tried reinstalling drivers on and I found there was and update for the mother board usb controller - after updating it instantly recognized it.

I am having the same issue with an added twist, which is that some USB ports will rapidly disconnection/reconnect the device to windows even though I havent unplugged it.
I have/had adb working on both my old laptop, and desktop. And like the OP I have spent many hours trying to get this to work. Very frustrating.

[Q] What to do when I can't see my HTC One in Device Manager?

Like in the topic. My pc can't seem to notice my HTC one phone. Not at all.
Some details:
PC - Laptop Lenovo Y580
Operating system - Windows 8.1 64 bit
Android - 5.0.2 I think (Lollipop)
My phone notices the cable (asks for internet tethering etc.) but I don't see it anywhere in pc's Device Manager (neither does HTC Sync Manager).
I've tried numerous things. I installed HTC Sync Manager, I've installed HTC drivers separately, reinstalled generic USB driver and drivers for USB 3.0, changed cable, changed port to another USB 2.0, change to USB 3.0, checked if it works on friend's pc (nope), reinstalled almost any of above mentioned things witt antivirus disabled, with firewall disabled, with almost anything that can be disabled. Nothing. It's not that case of wrong driver. My pc don't see this phone at all.
To be honest I'm tired. Like really tired. I've spent all free time I could find last week trying to somehow make it work. With no effect whatsoever. I don't see even slice of progress (noticing SOMETHING in device manager would be nice). I would love to see some way to analise this. I'm getting closer and closer to just buying new phone. Even though I don't want one, but I can't do any testing with this device.
EDIT: Few things I've remembered about my tries: I've tried both USB debugging on and off, and I've also already done factor reset of the phone - to no effect obviously.
When connected to pc, phone can be charged, but PC doesn't react in any way (no "USB connected", popping up HTC Sync Manager or "Media device connected" info).
I'll appreciate any help. Especially if it manages to change something in my situation.
Best regards,
Hisuu

When you plug in your phone to the computer do you get the following:
USB Connected
HTC Sync Manager
Media device [MTP] connected
Can you charge your phone while connected to the computer or do you have to use the wall charger to charge your phone? If you don't see the programs listed above, it sounds like a hardware issue with the USB port on your phone.

Yes, I can charge phone when connected to PC.
And as I mentioned phone actually notices it's connected to something, and asks what mode to enter (USB tethering, smart network sharing etc.). But it also seems... kinda dodgy. Sometimes phone doesn't react, I have to reconnect or even restart it. Sometimes "USB connected, Tap to change settings" stays... even after I have already disconnected it .
Few things I've remembered about my tries: I've tried both USB debugging on and off, and I've also already done factor reset of the phone - to no effect obviously. (I'll add this info to 1st post to gather info in one place).

Any other ideas?
This topic is my last resort, because I'm out of ideas and start leaning to buying new phone just for testing purposes (either Samsung Galaxy S3 or Nexus4 I guess).

start from scratch: Uninstall HTC sync and all the drivers you have tried. Then install HTC drivers only (not the generic drivers) or install HTC sync and uninstall it but keep the drivers installed (the idea is to have the driver installed but not HTC Sync, we don't want Sync to interact with the phone).
Try another USB cable but make sure its Data enabled (not only a charging cable). Some cheap cables are for charging only, no data connection.
Try another USB port, use 2.0 usb ports, do not use any external usb hub, use th eport directly on your motherboard (at the back of your computer).
Try with another computer
Clean your phone usb port using a cotton swab with some isotropic alcohol and then apply (spray) a light coat of electrical enhancer on your usb port (see your local electronic supplier or even some hardware stores)

Tried other cables (data enabled, they were from different phones), as well as different USB ports (both 2.0 and 3.0). Also tried another pc (no luck).
Uninstalled HTC Sync and drivers so many times I can't count it ;]
I'll try to clean the port and maybe use motherboard on friend's pc (on his machine I've only used front panel). Hopefully something works. Thanks for your input, I appreciate it.

[SOLVED] Charging but not recognized by the PC

Hi,
I connected my note 5 to my laptop today, and surprise surprise, it is no longer recognized by the PC (though it charges). It used to be fine, I don't know what changed!
I tried different cables, different USB ports and different laptops
I tried to plug it in normal mode, safe mode, recovery mode and download mode
I tried switching USB debugging on/off
I tried the *#0808# menu, and I tried MTP+ADB and CP options
I uninstalled drivers from the PC and installed the latest from the samsung website
I tried both kies and smart switch
nothing worked! I am not doing a factory reset because I have seen many people do it for other devices and none of them solved it this way! I'm waiting for the Marshmallow update, maybe it will fix this annoying issue. Meanwhile do you have any other ideas guys?

hi,
you don't say what Laptop o/s you using on laptop.?
Windows 10, Windows 8.1 Windows 8 or Windows 7...... or Apple o/s.?
Briefly my take is on this is, most probably the laptop and not phone.?
(Yes, i might be wrong of course.)
My reason is, i have Windows 10 laptop
and sometimes / a few time, ) my
laptop does not recognize my Note5
Yes, , it charges phone (just like yours) but does not recognize phone.!
I then have to re install drivers for phone I use Smart Switch to re install drivers.
Then it works ok for a while etc..
Why don't you test phone on someone else's pc or laptop to make sure.?
Overall my Note5 is mostly recognized by laptop
Good luck

Thank you for the reply.
As I have already mentioned, I did try another laptop. Mine is windows 8.1 x64 and my brother's windows 10 x64. I tried re installing the drivers from smart switch but to no avail.
Any other ideas?

hi ,
why i still think its laptop /pc drivers related.
(But yes ,i might be completely wrong ..?)
i have laptop win 10 x64 also.
The issue is of laptop, not always recognizing a device /similar as yours ,but charging device .
Other devices, when trying to connect to laptop (,not just my Note5 ),( from time to time) eg Note 2,..3 ..4 , USB flashstick ..my Polar M400 running watch etc .Device is not recognized but charging .
So for me,
its just not Note 5 but other devices also (.from time to time) .
My "take " on this issue is that it points between drivers (pc ,laptop) //// relevant devices eg Note 5 ..etc . and not just the firmware issue of Note 5 ,??
but yes, as stated i might be wrong .
good luck
Post note ,
i have to add reinstalling drivers "sometimes " help " ,
but it happens again, later. ( not recognizing device )
So i am pointing fingers, at Windows o/s + the "company/maker " of laptop ..pc and + devices .The compatibility between all three above ,combined and yes i had similar issues ( from time to time with Win 8 ../Win 8.1 etc ).
Yet, i have also found that certain of my devices
that work nearly 100% of time on my laptop !,
which indicates to me, the compatibility of devices between device /laptop ,is very good ..??

I have a note 2 and it works every time when I plug it to either pc. My laptop is lenovo with all the latest drivers. Hopefully, marshmallow will address this issue because otherwise, this means that I can't root my device.

Pull down notification menu while phone is plugged in and there should be a option for changing from charge mode to mtp and such. Just pull down notification and tap on the biodiversity that's lasted.

hi ,
strange ,
just for the record i also have a Lenovo Flex 2 laptop ( x64 ) Win 10 .!!!
i have rooted all my devices on Lenovo laptop ( Note 2, Note 3 , Note 4 and my Note 8.0 tablet etc )
Yet , i am at moment not interested in rooting my Note5 ( i have it already a couple of months )
I am happy keeping myself busy with Theme store ,tweaks/beta apps and lately with the interesting Lockmaster app( Play store ) for lockscreen ... etc .
If i get the root "urge " i pick up my other rooted devices and use them .or /update or/ install root only tweaks/apps etc. for my rooted devices .!!
i hope Marshmallow fixes your issues .!!
good luck

Edit: Never mind that. I see what you mean. That's odd it's not there for you. It definitely sounds like a PC issue. You can try completely removing all Samsung drivers and start over. Just using the Uninstaller will not cut it though. You'll have to do a system level cleaning of all samsung drivers.

The issue is not with your device. It's because of Windows. Is there another computer that you can use to connect your device to that you have never connected to before? Also make sure that you are using either the cable that came with your device, or at least a good quality cable. I've had that issue occur in the past because I was using a cheap cable.

I did plug it in my brother's laptop but no dice. I tried the OEM cable and an Asus cable on USB 2 and 3 ports, it did not work on either pc. How can I completely uninstall samsung drivers?

For users having the same issue, I found a solution (which also fixes all charging issues by the way).
If you look at the charging port, you will see a "tongue" where the pins connect. We all know that fast charging requires 5 pins not 4. The OEM cable comes with 5 as you all know. However, I found the OEM cable to be very fragile and not reliable, one pin tends to get bent without much pressure. This leads to the "tongue" going down somehow. The fix is to get the "tongue" up a bit, use a toothpick or something that does not conduct power. As for the cable, I suggest you use an Asus cable (I have 3 of those, 2 from my nexus 7s and 1 from my Zenwatch). Asus cables come with 5 pins and they are sturdier than Samsung's and they are a bit longer as well. Now the phone charges properly, fast charging and all and the computer recognizes it once again.
Hope this helps you too

I'm having this same problem these same problems. Other then I'm not able to get it to recognize even after doing everything that was said to do in this thread.
I feel like I'm missing a file? I was messing with them and just may think that could be my problem. is there anything else that has not been said in this thread I could do to fix this problem? When connected to my computer it recognize it as a charger. I can't access my files from my computer to my phone.
any help would be very helpful! Thanks!

I'm having the exact same problem but now I tried to use Flashify to go back to original recovery instead of TWRP & now by recovery or boot IMG is screwed so it wont even boot to recovery..
It boots only to download mode & is not recognized by any PC we have, with every cable I've tried.. uhhgggggg

I was having the same issue. Here is what solved it for me:
• Disconnect the usb cable.
• Go to Control Panel\All Control Panel Items\Troubleshooting\Hardware and Sound
o Go down to device / hardware and devices – click on that
o Follow instructions to correct issues. This found I needed a bus device driver update.
o Let it update and once done go out.
• On PC - Go to Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings - go down until you get to the part that says "All Networks" ...expand the list by clicking on the arrow to the right. In this area you will see "Media Streaming" There should be an area highlighted in blue that says "Choose media streaming options" click on that. Make sure you "allow all" . Once that is done, click "ok" at the bottom. Plug your device into the usb and it should be recognized. Seems a recent Windows update has that filter off.
• Now, restart your computer.
• Use original usb cord that came with phone! Plug in phone then plug in usb to computer.
• It should recognize your device now.
I now have to restart computer every time I want to connect my device but it works.

Hi I am having that same problem with my note 4. It doesn't seem to be a pc problem as no pc at all none Nada recognizes the phone. Windows 7 to Windows 10. None. Used 2 workmates of mine who also have note 4s on my laptop and all the laptops i used i used their phine on itand they worked so blaming the pc seems to be out of the equation..your solution and all those settings have been untouched as it has all devices allowed ..... tried cleaning the connectors and also different oem cables to no avail ..The only thing I have not done is change the logic board

Hi I hope somebody can help me. I am having exactly the same issue. though I don't think its PC or Laptop problem. I have two Note 5 the other one is working just fine, while the other Note 5 that was just charging was connected I noticed that running *#0808# I can select AP and CP but MTP+ADP was not selected and if I try selecting the radio button I will be able to but after pressing Ok or Reboot it back to no selection at all. Which I observe on my other Note 5 that was working its always selected every time I run *#0808#.
One more thing noticed is that on the Note 5 that was not working I boot it download (ODIN) mode and connect back to USB of my PC and Laptop, I hear a sound (the typical sound in windows once you connect any USB device) though I cannot access it I am positive that my USB port on both device are in good condition and since it was detected in windows through ODIN boot mode I was under the impression that its a phone software/firmware related. Can somebody help me on this one? thanks

Problem with OTG&USB N950F

Hi everyone
here I've got a terrible issue with my note 8 and SAMSUNG USB OTG.
When I connect my otg and a flash memory to phone, nothing happens, unless you force restart the phone while the otg is connected. After booting I can access to my flash memory but after removing the otg and reconnecting it, again nothing happens unless force restarting.
I've tried everything possible. Downgrading, upgrading, 4 files rom, pit file, rom from different zones, but still have the problem. I have no other issues regarding the USB port and charging, fast charging, connection to computer and any other stuff works fun but this OTG.
I wanted to know if anyone have any solutions for my problem or if anyone had the same issue or not.
it is also worth to mention that I have not rooted my phone due to warranty issues, and for that I haven't tested any kernels.
thanks for everyone

That isn't right... As soon as I plug in my OTG USB key it detects it, no restart required.

would it make any difference to enable the usb debugging in developer options maybe

allow file transfer .... possible

Nope, I have developer options enabled but debugging isn't on. never had to enable file transfer.
When I plug in the OTG device I see a usb icon in the notification panel. Swipe down and pick explore. Mind you it only opens in the stock file explorer, I did have another file explorer that picked it up too but can't think what it is and it has been lost myriad of other apps I test and play with...
Just be aware that it may take a few seconds to scan the device,depending on size, and then display the icon.

i know it sounds weird but from past experience flaky USB drives are more trouble than they are worth, from first hand experience i know patriot, corsair and sandisk work well as OTG drive
also you neglected to mention the file system the USB was formatted with, i believe only FAT, FAT32 and exFAT are supported

also possible that the phone doesn't like your OTG adapter. I bought a usb 2.0 to type C adapter which doesn't even work on the phone - when I plug it in usually the moisture sensor error comes up saying water is in the device and I should let it dry. Unplug the OTG and the error goes away.
So... I bought a USB 3.0 A to type C OTG adapter and that one works fine with everything I've tested (usb flash drives, keyboard, usb ethernet adapter, etc)

I believe the USB-C to USB-A adapter that came with the phone is actually an OTG adapter (tested xbox360 controller and keyboard)
I also believe that the note8 can host usb flash drive native (no need for OTG cable) as i have a dual head USB-C and USB-A flash drive which is recognized once the USB-C end is plugged in

I'm test with any OTG cable or.....not work
also reconnect and again connected but no answer
only with force restart

Sorry to dredge up a semi old thread, but has anyone found a fix for this?
I'm having almost the same issue, I finally decided to try out the OTG adapter from the box and nothing works, it isn't even recognized. Tried ps4 controller, mouse, keyboard 2 different thumb drives. Can't figure out what the deals is.
Other than that pc connection seems to work and charging works fine. TIA

I'm having a similar problem. A month ago, used both OTG adapters (original from Samsung and a generic one) it detects my memory sticks as a hard-disk and was able to manage my files. But since a couple of weeks ago it does not detect them anymore. Is like it did not supply charger to them anymore. I have tried the USB debugging menu and no difference at all. Even I got back to factory reset expecting to solve the issues but nothing happened. The port as such is working perfectly because I'm able to charge through it. On the other hand, Samsung DEX is not working as well. It just charges the phone but never boot-up.
I'm just waiting for Oreo and hopes this will sort the problems out.

That sounds like a bodged port to me man
Is there any dust or dirt in there that you can see?
I really don't think Oreo's gonna fix that for you

Seems to be a little bit dusty. Anyway, the other thing is that, when the Usb is detected it ask to choose between transfer files, images, midi device and so on, even if I choose "transfer files" mode it always get stuck as "charge connected device".

Hi i have the same problem... my note 8 can connected mith my notebook, but my otg with an usb stick cant recognize my note8. I test the same otg with usb stick on my friends phone example S8 and it detects promptly all.
I hope the fixing take not long time. I waiting for help. Greets

Well, adding one more case here, my native file manager doesn't recognize any memory connected via the original otg conector, but, using x-plore file manager, problem solved, as I use x-plore since my symbian days, I never gave this issue much importance, this problem was present also with my note 7

This. I have exactly the same experience. I bought a couple of months ago a new Note 8, and finally decided to try the OTG adapter that came in the box. Nothing worked. I tried the adapter with a friends phone and it worked like magic (USB drives, mice, keyboards, controllers, etc.).
Would really apreaciate if anyone can provide help on this issue... Cheers!

Question My S21U does not connect to PC

When I insert my USB cable into the PC, there is no response, no notification sound saying that a device was connected. The phone simply charges and does not seem to enter file-sharing mode. There is no activity on PC or phone when it gets connected. Not even a USB sign, just "cable charging". Any ideas?
I am certain it's not the cable because when I connect my old S8+, it all works fine but my PC just doesn't react to S21. I've also checked the developer options and it's set to "transferring files" mode there.
I installed USB drivers but it didn't help. The only way my phone gets detected is if I enter download mode but that''s not very useful to me

Sounds like a driver issue.
Check Event Viewer for error messages.
Try looking under drives and opening directly from there.
Try turning off Developer options.

There are no errors in the event viewer, the computer simply does not react when I connect my phone. All it does is charging. Turned off dev mode too, no dice.

same thing here..
factory reset my phone
reinstall adb driver on pc
still missing usb options upon plugging in the cable

I'm thinking of returning the phone at this point... I've even flashed through Odin just now and it worked perfectly but it won't connect to PC.

I had the same problem, until I used the cable that came with the pods pro.
Its very weird because I have other high quality usb cables but they didnt work with my S21U exynos edition.
Only the samsung one worked.

I don't have pods pro though... The only cable I have is some generic USB cable that works perfectly for my S8+ and a USB-C to USB-C cable that came in the box with the phone. None of them work. I don't know what to do

Nevermind... I have just cleaned USB-C port on my PC and it worked! Still weird how it won't accept my high quality USB cable though

My S21U connects fine to my work PC but doesn't connect to my home laptop, both run Windows 10. The laptop doesn't react at all to the phone being connected, the work PC behaves as normal. The only difference is my work PC is on W10 Pro, the laptop is on Home, both are up to date. I've been blaming Windows so far but I have no idea if it's that or the phone.

Are you using the same cable on both your home and work PC? If yes, try different USB slots and make sure to clean them too, that's what helped me.

Same cable but I will check the ports on the laptop later, it is a good possibility that they are full of fluff.

Yes exactly and i tried the cable with 2 different phones and they work perfectly. When connected to S21U it only charges....

You need to use a full pin usb c cable. A usb 2.0 type c cable will not work

Connected fine to windows 10 pc here used my Xbox elite cable no problem. Hopefully you find a solution.

Same problem!
And cable is not USB 2.0. Cable from P40- Pro. I tried different cables, different PC, no effect. Model SM-G998B/DS. I contacted support 3 times, no effect. The "data exchange" option does not appear on the phone".

in the file explorer are you able to see more than just media files from your phone? are you able to see documents files, ex.. docx, pdfs? how about zip files and .exe files? are you able to bring any files from your pc to your phone? i'm not able to do those. any feedback would be appreciated. thanks!

Lol, Same here, expensive Cabels with quick Charge 3 etc. did not work, the cheapest cable i found worked ...

Thanks for the reply, I decided to just do the factory reset on my phone and that helped the issue. As well as Windows 10 updating the Samsung USB drivers to the latest 2.17 version.
