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.
Windows 7 64 bit
Laptop
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.
Hello fellas,
I have a problem with my brand new T813 running the latest official firmware available (Android 7).
Massive storage is not working, my computer running Windows 10 with updated samsung drivers has failed to detect it. The device charges, but I am unable to modify the usb options, regardless the choice MTP always remain.
I have tried with three different cables, all of them work fine with my S7, the computer never detects the device, eventhough it's charging. This means it is not a problem with the device's micro usb port. I have the latest drivers, and I have also tried with all usb ports. None of them seemed to do the trick.
The computer has faulty usb 3 drivers, ever since I have installed Windows 10, the speed is not what used to be with the previous configuration. I have the same drivers, I don't understand what's wrong.
Any help would be appreciated, I have tried most solutions mentioned on this community and they didn't work. I can't flash the device because it is never detected. The problem still persists after a restablishment via the menu.
Download mode shows
QUALCOMM SECURE BOOT: ENABLE (CSB)
FRP LOCK IS OFF
[UPDATE] 06/08 11 AM
Left the device at SAMSUNG ARGENTINA repair shop. Also had to pay 300 pesos (around 20 dollars) as a diagnostic fee, they told me that if I accept the repair cost later on, they would discount the 300 pesos I have paid out of the total price. And if I don't, they will keep the money.
Will update again when Samsung calls me in a couple of days. Maybe this monday, I hope so.
[UPDATE] 06/08 15 PM
I have just received an email from BGH, which is the SAMSUNG ARGENTINA official partner for repairs. They told me that the problem is a FAILURE on the SUB board.
http://www.ebay.com/itm/Micro-USB-C...g-Galaxy-Tab-S2-9-7-034-SM-T813-/322414846816
The good thing, is not that expensive. The bad thing, this tablet hasn't arrived officially to Argentina, and since it has been bough in Chile, the guys at SAMSUNG ARGENTINA had to request an international order replacement, which I have been told it could take some time. But they will eventually get the piece.
Will update again.

Thanks for replying, please refer to first screenshot. No Mass Storage option appears after connecting device. MTP option seems to be forced, i am unable to change it.
The tablet is brand new, but the guy who sold it to me said that it has always been working. He even told me that it has been barely used, and that the device is recognized when connected to an usb audio system. It has been upgraded to 7.0.1 a couple of days ago, maybe that's the problem.
I have just tried with a macbook air and it didn't detect it either, it is only charging. The same computer has detected my S7.

Modern devices don't use mass storage anymore, they use the MTP protocol.

When the problem appears with different USB cables and in different computers, as in your case, you have to look into the possibility that it may be a hardware issue.
I hope I'm wrong about this, but it sounds like the DATA+ or DATA- pin is damaged in your micro usb socket (pins 2 and 3, see http://pinouts.ru/PortableDevices/micro_usb_pinout.shtml)

Yes, I'm afraid it could be a hardware problem. But that would also mean the guy who sold it to me is lying. I have to say it, the device looks like it has been treated with care. However, i have noticed the plastic has worn out a little near the usb port, those black marks could indicate not so much care when plugging or unplugging the cable.
I hope we are both wrong about this. Tomorrow i will know. Fixing this is a pain in the ass, right?

¡Che! Replacing the microusb receptacle would not only be a pain the ass, but if you make a tiny mistake while soldering or desoldering you can end up with a bricked tablet.
Anyway, let me know what you find out tomorrow, good luck boludo.

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.

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

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.

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.).

Hi, phone works OK, it also charges BUT doesn't connect to any PC (windows detects device with description error?), usb OTG not working either, only headphones using type c adapter. Please help, I'm using stock pie with February update, unrooted, blocked bootloader and with usb debugging enabled.

Thanks for the update.
Go into Step 7, with the device connected, and install the drivers manually.
So, in this scenario, you'll right click on the device and browse to the location where you downloaded the drivers.
I need to know what happens if you try and install them manually.

Hi, I can't actually do step 7 because it doesn't recognizes the phone as an Android device like in the guide, but as an:
Unknown USB Device (Error Device Descriptor Request Failed) see attached screenshot.
Even when I select this Unknown USB Device and tried to update de driver manually, the installation fails. (see attached screenshot) .
I've changed cables and tried on different ports of different PCs. Same result. Also by entering Developer Options and accessing the USB settings won't work, there are all greyed out.

Thank you for your efforts and feedback.
Based on the details, I would strongly suggest you initiate a return. You've taken all the appropriate steps, and then some, to address the problem but it's obvious the issue exists with the device hardware.
I am happy to provide further instructions but what concerns me is the fact you've tried multiple PCs and multiple cables.

Hi, I can't return it so I already ordered online a replacement Port Board from aliexpress.com, so I'll check back in 4-6 weeks, thank you very much for your help.
did replacing the port solve your issue? I have the same problem
---------- Post added at 07:21 PM ---------- Previous post was at 07:21 PM ----------
cant even force edl mode
Sadly I'm still waiting for the replacement to arrive...I'm in Cuba. But other people with similar problems have solved them by replacing the USB port. Good luck.

if you followed all of the instructions and steps in this post and the problem continues, then you should return your phone.
I already changed my USB port. My warranty is void
If your phone was in warranty you should have returned it, changing the USB port was your final option. Now you should take it to a service center. Good luck,

I replaced my usb port today, still no luck, I tried 3 different ports (I bought 3), It charges with all of them but no USB connection to PC or OTG. I'm thinking its the mainboard. Could it possibly be the FLEX connector?
This is a big problem with 2 MI A2 for me
Since that problem i hate Xiaomi and never Xiaomi product to bey

I waited 3 months for my USB port replacement and it did the same thing, now I'm waiting for the flex connector, if that doesn't work either, then its a problem with the motherboard.
I ended up replacing the entire phone and a few months later this phone now has the same issue.. this is horrible. Especially with no USA support from Xiaomi. Its a "deal with it" situation.
But i believe the use of crappy chargers, debris getting into port, maybe Qualcomm quick charge modules design flaw could be sending unsafe currents or lacking proper temp regulation when charging,, is damaging something on the main board. I checked every possible software related possibility and tried every fix with no luck.
What i did notice when it happened this time, chargers were not staying connected, they would pop out due to debris in the charging port, also i noticed my phone got pretty hot using a Qualcomm QC enabled charger one night. Nothing else was suspected of generating heat, all apps closed, screen had been off.
I everyone... Where i can buy an usb port?? My A2 is not charging, trying at least 4 different cables and chargers,
Tks
Hi, My phone is showing these symptoms :
If I connect it using USB cable, no USB icon shows up in status bar, PC does not recognize any device connected to it(with or without driver you should be able to see a USB device connected to it) also it wont even charge!
Phone charges fine with charger
If I turn off phone and connect it to PC it will start to charge
Holding volume up and connecting to charger will result in LED turn blue and a black screen but still no USB device shows up in PC for fastboot
If I go into USB Preferences and connect the USB to PC everything is grayed out except enabling charge connected device
what I've tried :
Use different cable
Use different PC
Use different OS(windows10/Linux)
Reboot phone
Removing SD card and SIM card
Factory reset phone
Clean USB port
My phone is using latest Android pie Build 52.0.A.8.14, developer mode and USB debugging is also enabled.
I would appreciate if you let me know how to resolve this If you think it's not a hardware issue
Is there any way to install TWRP without having USB connection to the phone ?

Thank you for your reply, and I assume there is no way to install recovery without data connection.

If you don't rely on unlocking, usb data transfer, etc it is fine
I know this is a old thread, but
I have a similar issue, I need this phone for debugging purpose, and I "fixed" it by turn the usb-c around........
Just like the old usb.
I don't know why. I already tried multiple cables, all have "one side connection", it seems it's phone's hardware issue. But I'm not sure.
That's not the case for me, looks like some people are telling this has happened for them after updating to 52.0.A.8.50

I'm also having the same problem with the same phone (android 10 build 52.1.A.2.1).
This problem started yesterday and somehow my SD card is not recognized anymore, it's asking to reformat it.
Rotating the original usb cable does help!
Only it doesn't want to connect to finder on my Mac, I have yet to try a windows pc.
