[Q] Tried tons of links to drivers on multiple threads. cant connect phone to pc.

So for 3 days now i have been reading thread after thread on xda. i cant seem to connect my phone to my computer. Every time i come across a new link to drivers i try it but still no dice.
What happens:
Install Drivers
Phone set to mass storage
plug usb in
mount sd
windows thinks...
USB Device not recognized
Phone: Captivate, stock everything (with ota update)
OS: Windows 7 64 bit
What am i doing or not doing?
I apologize in advance if i have not stumble across thread where this has already been answered.

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

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.

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] Windows "USB Device Not Recognized" error

Does anyone else have this problem? When I connect my phone to either my laptop (winXP) or my desktop (win7x64) I periodically - constantly, really - get this message:
"One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."
When I click the message, it identifies my phone as a Generic USB Hub (4 ports) with the first child being a USB Mass Storage Device, the second being the problematic "Unknown Device" and the last two are "Unused Port"s.
This happens whether the phone is in charge-only or mass storage mode. I tried installing the autoplay drivers and that didn't help, so I uninstalled them. No hubs are involved - I've always plugged straight into the tower or laptop. I've also tried two different quality (first party Motorola) cables.
Mass storage mode works fine despite the error - I can access the Internal storage as well as the SD card. Is this a problem with my phone, or am I missing some software on the Windows side?

Thanks for the suggestion major. I tried those drivers with no luck - the message still pops up frequently in both charge and mass storage modes.

Odd... I had issues with the original drivers, but once installed, I never had another prompt again.
edit: I had it one more time, but it found them and installed them

that's very interesting. i also use 2 machines--one with xp and one with win7. my usb connection worked flawlessly on both. fyi...my connection default is mass storage, and i've actually never tried the other options. i wonder why the difference? did you make any changes? are you rooted? i am not.

Hi gr33nT,
Thanks for responding. I'm 100% stock at the moment, not rooted or anything (though it will be soon ) Sometimes I use charge only if I have it connected to my laptop at work but I still want to listen to music from the SD card. I may see if I can get Verizon to swap out the phone, the message pops up all the time and it's getting annoying...

A quick follow-up on this one: I tried the stock LG cable on my win7 machine (I had been using moto cables). I installed BOTH the bootstrap drivers as well as the LG drivers from the web - still happening. I rooted with these drivers via S1C so I know the drivers are good. If nobody else has run into this, something is probably wonky with my phone, so I'm probably going to exchange it.

For mine, every time I connect, it asks me if I want to install bootstrap. Even though, they have already been installed cuz I am rooted.

I've had the same issue both as stock, and rooted and in every configuration with the phone and PC you can think of. I've downloaded the drivers and installed them from both the phone and web site all to no avail. This is really getting annoying.
I hope someone has a fix for this.

Hmm...that is troubling. I'm still having the issue running the stock rom and rooted, now. When I get time I'm going to drop by the Verizon store and hopefully they'll replace the phone - I suggest you try the same, as I doubt it's the computers we're using. My win7 box and winXP work laptop could hardly be more different!

I doubt a replacement will fix anything, I experience the same thing as majorpay. Drivers worked for a while and then it started asking for it again. This also causes issues when using usb tether as its connecting and disconnecting. The issue is not present when used as a mass storage device.

Hi bwhxeon,
The issue (USB device not recognized - it sounds like you're referring to the autoplay driver installation) happens for me in mass storage mode also. I believe it has to be the phone as I've never had this problem on any of my PCs with my OG Droid or any other USB device. With this phone, I have the problem on all of my PCs.

I had the same problem. The error popups seemed random at first. I noticed if I enabled/disabled the WIFI on the device while it was connected, I could make the error popup.
I ended up getting a new replacement device when I also noticed the 4G Hotspot wasn't working either even after a factory restore. There was definitely a hardware issue with the phone.

USB Unknown Device
same issue here.. when using ADB though I have to set to Internet Connection then it goes away for a while until I want mass storage or just charge from USB again, then re-appears.

LG is not like most other phones as in usb debugging only works in internet connection mode where others go into it as soon as you plug it in.

Just kind of scanned this thread but have you tried a different USB cable? I was having a problem with mine only wanting to charge with the stock so I grabbed another cable and it has worked right ever since

Same issue, two different pcs, with two different cables. Bootstrap does not load anymore so I am using the drivers from the links, both sets of Lg verizon drivers

[Q] USB seems to have died???

When I try to connect to the computer I get nothing, just a beep on the phone, I was getting an error and now I don't even get that on my computer. (USB still charges the phone though)
I tried 2 different cables, 2 different computers and 4 different operating systems, Windows based. And lots of Captivate USB drivers.
I have tried Kies, odin one click, mass storage, debugging on, off, everything I can think off.
I tried 2 different Roms, (Apex 7 and 10.1) 3 different kernels and 6 or more factory resets. MTP is listed under apps but when I plug in the USB cable I don't see it under running tasks.
I have a Captivate I896 running Gingerbread I9000 software. I would like to go back to stock but without USB I can not run the software, (computer does not see Captive in download mode or in recovery mode.)
Would anyone know how to troubleshoot this, is there a way to debug the software and see just what is happening on the phone.

Dam you have tried a lot of things... lol
I have a suggestion... have you try 'adb'?
Let me see If understand right...the problem is that ODIN is not recognizing your device and you want to go back to stuck? you don't specify if you can transfer files between your computer and phone...and also if you can connect with 'adb'.
Probably was you micro usb on your phone got damage...have you been experimenting with a jig?

ya I have tried adb and when I type in adb shell I get a response of no device found. and no the only thing that went in to the usb connector ever, was the Samsung usb micro cable. I think I will take it to Samsung next week if I can find the service center around me, I think it is still under warranty.

Check to make sure the cables you're trying are data/charging cables. My stock cable went out so I found one I had in the closet. The one I found would charge but no data passed (ie. PC wouldn't see it).

[Q] Defective Note?

I bought a new N7000 and everything works fine except I can't get it to connect via usb. Kies won't connect to the phone but everything else works fine with it. I can transfer via wifi with Kies.
The charger that came with it also wouldn't work, so I got my G2X usb cord and wall adapter and it charges that way, otherwise, the computer won't recognize it.
After rooting it Windows 7 finally installed the drivers for it, and the computer showed it was charging (still no usb storage though) and once I unplugged it and plugged it back in again no response.
Tried mounting usb storage through CWM and still nothing. I would think if there was something wrong with the charging port that it wouldn't work at all, but I can charge via a/c adapter. Confused.

A good test for this may be to try the Android SDK to try and get an adb connection. The reason I say this is it bypasses the samsung usb drivers and uses a generic set. If you can get an adb connection and pass a few basic commands then you'll know it's not hardware issue.
There are a few possibilities for this error...
1. MTP service is not starting correctly on the device which would suggest needing a rom reflash or factory reset. Using the Android sdk connection will help determine this
2. MTP not starting correctly at pc, suggesting driver installation/corrupt download of samsung drivers, again android sdk will help determine this
3. Usb port of pc issue. On my rig, connection usually fails off front ports, but rear ones work fine.
4. Cabling, does sound like the cable/charger that was supplied may be faulty.
5. And finally, the hardware usb on device is faulty.
How were you able to root.?

Once in download mode Oding would recognize the device. Other than that, the computer never will.

[Q] USB connection problem

Hello,
I'm more convinced that it's drivers problem, but my SIII Mini is giving no signals about connecting to PC while using USB cable, except it's just charging.
USB Debugging is obviously on.
Tried factory reset and installing few "versions" of Samsung usb drivers.
Don't have 2nd PC, nor 2nd cable, but cable was working with another phone (not samsung though).
I'm using Win7 x64.
Odin doesn't see anything either.
There's no SD card in my phone.
Rooting through app doesn't work.
Wifi connections (Kies/Ftp) does work, but i need that to be able to run/debug apps (i'd want to start to develop in Android) - if there was a chance to connect phone without using USB cable to Android Studio/Eclipse, then i could skip USB connection and use that instead. Emulators can't do all the jobs and are running slow on my PC + real phone means i can exactly know how app will work in the real usage.
Last times at reinstalling there was no such a thing, but when last time i've tried to connect my phone to pc and installed drivers few weeks ago, after installation finish, windows was showing in it's "drivers installation processes" that drivers installation failed, because "couldn't find the driver" (if i can remember, but that's what it said more or less).
Traditional question: have you an idea, what could be going wrong here? If need more informations, i can deliver.
