I'm having an issue where my thunderbolt does not recognize my device any longer. I used to have it set up with pdanet and everything worked well for about a week. All of a sudden, any computer i tried to plug the device into, wouldn't detect the phone. A friend of mine has tried his thunderbolt on my computer and it detects it.
When plugging my phone in, it pops up an error message with "USB Device not Recognized." In the device manager, the phone shows up as Unknown Device. I have tried this on 3 different pc's, using 3 different data cables. No USB symbol displays on the taskbar of the phone when I plug it in, however, it does charge.
What I have tried:
Changing data cables.
Using another PC.
Uninstalling device drivers and letting windows re-detect and install.
Downloaded HTC Sync and ran it after uninstalling drivers again and re-plugging the phone.
Changed different Connection settings on the phone, such as USB Debuggin on/off, and changing it to HTC Sync Mode, Charge Only, Disk Drive, etc
Mounted and unmounted SD Card in the phone settings.
OS: Windows 7 x64
Thank you for any help you may provide.
same problem
I have the same problem with HTC mytouch 3g 32B Android 2.2.1 when I plug it through usb under Vista.
Any suggestions?
Try installing the usb drivers from htc if you haven't.

I have download the HTC usb drivers but when i go to control panel and uninstall the unknown device it just reinstalls it. when i try to update drivers using the location
ie C:\Users\sxristi\Downloads\android-usb-driver\Android USB Driver\i386
i get a reply
The best software for you device is already installed. Windows has determined that the driver software for your device is up to date.
and it continues to point to
unknown device
Oh one more things i got the usb drivers from Android SDK Manager the google usb drivers revision 4 and the weird thing is that i do not get the trident usb nor the debug icon on my HTC when i plug it in to my vista. I did get it once or twice before but not in general since the usb devices are not recognized. However when i boot on my Ubuntu os then i do get them recognized. so i guess the problem is with windows drivers somehow...
Thanks for the replies.
I've tried to install the drivers from HTC but Windows says that the driver is not compatible with my the device.
Also, I tried on a system with Windows XP and everything worked as intended, but I cannot get it to work properly in Win 7 x64 anymore.
When my win7 comp no longer sees my Tbolt I have to toggle the USB Debugging off then back on. Usually within a few seconds it reads it again. If that does not work I have also used the option to turn on internet pass through then change it back to hard drive mode. Either of those usually work for me. My drivers I used were from android sdk if that makes any difference. Hope this helps.

HTC
My problem continues under Vista OS. I called HTC and they told me to re install their Sync after removing Adobe Air and all HTC drivers and Google USB drivers. I did that and reinstalled Sync and still nothing. They also told me to call microsoft for it seems operating system conflict.
My conclusion yields toward windows conflict. But I can not figure out this conflict. Perhaps something I have installed does not let my vista recognize the HTC android device and uses the windows usb drivers to create this "Unknown Device" under usb serial bus controllers. once it is an unknown device forget about Sync or ADB etc... The phone is just not recognized as android and you can not do much with it via windows.
For the person who suggested to turn "USB Debugging" on-off, i did that and still the computer recognizes that there is a usb device but again it says "usb device not recognized unknown device.."
any additional suggestions???
I've verified that my phone works fine on Windows XP. I still cannot connect to windows 7, though.
Try turning OFF Fast Boot and turning ON USB debugging. this helped for me.
same problem
I have a similar problem too .. i know its not the computer as other phones and pen drives are working ok.
Plus this phone has same problem on other computers too, where as other phones work fine.
So it has to do something with the phone and not the drivers or computer in anyway
I have the same problem, no PC recognizes my HTC Thunderbolt. Now change cable and tried with windows xp, 7 and 8. Is there any solution I can not root. I want to change the rom factory rom I do not like but I can not do anything because I do not recognize the usb. Also the menu does not appear when I connect via USB in the notification bar.

I'm having the same issue, with an HTC Rezound... just flashed a new rom, need to update boot.img but can't see my device via adb or fastboot... have tried changing usb cables, phone is in FASTBOOT mode... reinstalled HTC Drivers, just get USB Not Recognized error (Windows 8 64-bit)...
Any solution for this?
Okay, so I am attempting to flash back to stock, or anything that WORKS at this point.
I can get my phone into download mode and I connect it to my computer, but I get a rather annoying bubble that says "USB Device not recognized... one of the USB devices connected to this computer has malfunctioned and Windows does not recognize it."
I goto device manager and check my USB devices and it is listed as "Unknown Device" I look at it's properties and see "Windows has stopped this device because it has reported problems. (Code 43)"
So, I check the driver details.
It says "No drivers are required or have been loaded for this device"
So I goto update drivers, browse to where I keep them and see "Windows has determined the drivers for this device are up to date."
I have reinstalled all my drivers using various methods. I have tried new USB cables and all of my USB ports.
No matter what I do ODIN won't see my phone. Nothing shows up under any of the usual COMs
PLEASE HELP! WHAT SHOULD I DO?! D':

If you're running anything Gingerbread, you need to download and install the Nexus S Drivers to get your pc to recognize your phone in dl mode.
Didn't work. Could you link me to the the drivers?
I got mine from androiddrivers.net/samsung-android-drivers/download-nexus-s-drivers/
I GOT IT!
Upon taking a closer look at things.... literally. I found a very small piece of what appeared to be pocket lint lodged in my phone's port. Pulled it out and immediately regained functionality! SO, words of wisdom from hours of frustration "Look in the hole"

Those are probably the right ones, however I got mine directly from the drivers folder in thr Android sdk gingerbread update. Are you getting an error when you try to install the drivers you downloaded?

Thanks for the help though!
Just download the drivers. click usb debugging. it should pop up.
Hi, I have a Galaxy Player 4.0 that I rooted with SuperOneClick. It was working fine at first then a couple of weeks ago, I noticed that my PC no longer recognizes it as a device, it just charges when I plug it in. So, I looked around andn tried a few things:
Restarted it several times
Tried with all the different modes in USB settings
Tried with different cable
Tried with two other computers, a Mac Mini and a Win7 laptop
Tried to unroot, couldn't get that to work
Did a factory data reset
Nothing works. I can't remember anything I did since rooting that would cause this, except I installed the Samsung Kies driver on the PC. I can't remember if the USB mass storage was working after Kies. Does anyone have other ideas?
Bump. This is rather a big deal, as I cannot transfer files between my PC and Galaxy player in any way other than over WiFi, which does not work reliably. I don't have a microSD card adapter either.
You might want to check if anything related to samsung/android appears in the device manager. Alternatively, to use heimdall I use Zadig to switch from samsung's driver to libusb but it does show you everything connected to your computer via usb when you check the option to list all devices. You should try this with and without usb debuging enabled. If nothing shows up you know it id your player that is at fault.

Thanks,
The first time I plugged it in without USB debugging enabled nothing showed up, when I enabled USB debugging, in Zadig and Device manager there showed up an unknown device, trying to update driver in Device manager showed that it already had the best driver, and in zadig driver replacement failed. Now, when I plug it in, either with or without USB debugging enabled, nothing shows up anywhere. I have tried with other computers and other cables, and nothing works, so I am pretty sure it's the player. I am willing to to a complete factory system reset, but I don't know how.

I'm having the same problem with my rooted 5.0. Although it's not a huge problem for me (I use dropbox for file syncing) I would love to sort this out, let me know if your factory reset works!
You can find it in the Privacy section of the settings menu.

I suspect you have a faulty usb connector on your device, but it doesn't hurt to do a factory reset. But you might want to backup your data first Did you try to jerk the usb cable in your player? A loose/broken connector would explain all your problems. Even if it is a software problem, I can't see how to flash your device with the original firmware since you don't have a sdcard & usb doesn't work...
Btw, I was referring to zadig only to show the devices attached to your computer, not to change the driver!

Thanks, I only tried to change the driver because it showed no driver already installed. I have a bit of electronics background so I may crack it open and take a look at the connector. I already tried the factory reset in the privacy menu, but that only wipes data apparently, not the system. I do have an sd card, I just don't have an adapter to the PC.
EDIT: After wiggling the cable around a bit, it showed the USB icon in the status bar, so I clicked connect USB mass storage, but the computer still showed a badly installed driver and then after some more wiggling the icon disappeared, so I am pretty sure it's a problem with the connector. BTW, how would I flash the stock firmware to unroot?
Need a little help here. I cannot get my phone to connect to my computer, I'm running Windows 7. I have kies installed and have also downloaded the drivers directly from the Samsung site, but still cannot connect. When I plug in, it says installing drivers, but then gives me an error.
If I go to Device Manager, I see SAMSUNG Mobile MTP Device but with the yellow exclamation mark. Under driver details it shows the correct driver installed, but has a Code 10 Error. "The Device cannot be started".
I've rebooted comp, rebooted phone, toggled USB debugging, uninstalled and reinstalled drivers, tried 2 different USB cables, and nothing is working. Anyone have any ideas?
I didn't have to do everything you listed to get it to work, but I did have to run the installer (T-Mobile_T999_GSIII_Samsung_USB_Driver_v1_4_6_0.exe) twice to get it to work.. it failed the first time.
I just unplugged and then plugged cable back in, ran the installer and installed again over old drivers.
You can also try going into Device Manager, right-click on the phone and "Update Driver Software" manually... installer extracts all drivers to the C:\Program Files\SAMSUNG\USB Drivers folder.
Still no luck. It installs the Samsung USB modem drivers fine and shows the phone correctly, but fails on the MTP Driver section.
Just for future reference for anyone that comes across this while searching. I did get this fixed. I tried a couple more usb cables and a friends computer with the same issues.
What I ended up doing was a factory reset on the phone. Plugged phone in after first boot and mtp drivers installed right away.
Hi,
After the most recent update (OTA), when I connect my phone to my PC, regardless of what mode I have the USB set for on the phone, I can no longer connect
to my phone.
It worked flawlessly before.
The Huawei HiSuite also cannot connect (although I don't norm ally use that anyway).
I have tried reinstalling ADB and also HiSuite to no avail.
One thing I do notice is that there was a HDB driver missing. When I rebooted my PC it has now changed to 'USB Composite device' but shows the error
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
{Bad Image}
%hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0x
I've tried to automatically install a driver, again no joy. (Because the device is not recognised, it just says it could not a find a suitable driver).
If I uninstall the device and then plug my phone back in we then start with the HDB device (for which there is no driver according to MS), which upon reboot becomes the 'USB Composite device' again.
So, anyone know how I can fix this? I'd like access to my phone through my PC if possible.
TIA (Thanks in Advance)
I know it's obvious, but have you tried a different usb port.

Yes. Front and back of PC as well through a hub.
It makes a sound like it connects, then I get a popup on my phone "Charge only / Transfer files / Transfer photos" and regardless of which one I select, it then disconnects.
Somewhat annoying. It worked okay before latest update.
I've even reinstalled ADB, even though I'm fairly certain this has nothing to do with it.
Thanks for your reply anyway!
[Solved]
I managed to solve this by plugging in my Honor 9. On the device manager page in Windows take a look at the 'USB Composite Device' item and selecting with an exclamation mark against it and right click it and select"Uninstall device" from the menu. When it asks to remove the driver, select yes. Unplug your phone. Reboot your PC. Upon plugging your phone back in, your device will be re-detected and Windows will install the driver correctly.
