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.

These didn't work, but thanks for the input
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?
Yeah, so i've read plenty of topics about USB problems, but none gave me the
anserw.
I'm running Villain ROM 3.0. I just cant connect my phone to the computer (Mac).
It work well before also after flashing Villain.
What i tried:
1. connecting my phone without usb debuging ->phone gives the sound and report in the notification bar : "MTP - initializing" then "USB Connected, MTP-connected" But it does not gives a connection with my mac.
2. Connecting my phone with usb debuging ->phone gives the sound, but nothing happens. nothing in the notification bar neither on the computer. It's strange becouse before it was making the same sound and giving me the info in the notification to connect.
3. I've also tried KIES air it works fine. i can see my phone content, but when im trying to send one file (130mb) there is no reaction to this.
Also some time ago i was able to get usb working by simply choosing usb debuging and restarting phone.
But now i have no acces to my storage
Please help
I have a similar problem.
When I connect my SGSII to my PC (with USB Debugging On) I see 2 Removable Drives in Windows' Explorer. If I click on either one I get the "Please Insert Disk". If I connect to the same USB with USB Debugging off, then Kies Starts but does not connect.
Now the weird bit, if I do the same thing in the next USB port, then everything works fine.
Going back to the first USB slot then the problem reappears.
The 2 USB slots are next to each other and go back to the same controller on the motherboard. I have removed Kies and reinstalled Kies. I have uninstalled all the drivers. I have even changed the USB cable. When I plug a USB External Hard Drive into either USB, it works fine.
Maybe the phone just likes the one connection per computer. I'll have to test that out in my work's PC.
Update:
managed to get a microUSB cable and tested it on my work's PC. Exact same situation. Both PCs run Windows XPpro.
Has anyone else noticed this?
Now, when you said that, i checked with my second usb por, and everything works fine .
So thanks for your help. One working with sgs2 usb port is enought for me
I have a Verizon LG G2. I attempted to root it based off the instructions here http://forum.xda-developers.com/showthread.php?t=2448887.
I Installed the drivers on my PC and it showed successfully.
I pressed the button 4 times and developers options were enabled.
I plugged into my PC, however, the only option that I could get USB Debugger mode to show was connect via USB for Internet using ethernet.
Every other connection option, even just plugging it in period wouldnt show it.
I got that done. I then opened command line and did adb devices and it showed my device and was recognized.
I navigated to the batch file and I ran it, but when I hit any key to continue it just kind of disappeared and gave me no further instructions.
The message was too fast for me to see what it is saying. Can I get some help? I am fairly intelligent and work in IT but have never rooted a mobile device before.
I originally posted a threat up on reddit, but I couldn't find a fix for it.
I got a Note 2 do Android development on. I for the life of me cannot get the damn phone to connect to any PC I connect it to via USB; the phone charges, just does not connect. The USB icon does not appear on the device when connected either. I tried 3 different Windows machines, with the same warning I get that the device isn't recognized, but reads it as an 'Unrecognized Device'. I have also tried OS X, does not read it as well.
Here is some of the things I've tried from reading around XDA and other forums that haven't worked for me.
Solutions i've tried with no fix:
Various USB 2.0 cables (I do not have the original cable)
USB 2.0/3.0 and other ports repeatedly.
Enabling USB Debugging
Installing Kies, and Samsung driver from their site
Resetting battery
Booting into recovery mode with device connected
Dial codes for some reason do not work on my phone. I tried entering them with the stock dialer to bring the USB settings, but they don't work. I got around it by installing an app to get the USB mode to MTP, still does not work.
Rooting right now is not option, since Odin requires to be mounted to a machine in order to root. So I'm pretty much stuck. Still can't get this phone to sync on anything.
Device info
Model: SCH-I605
Carrier: Verizon
Android version: 4.4.2 (Kit-Kat)
Stock ROM/Non-Rooted
I'm not sure if it was the recent windows update(1803) or if my phone is ****ed.
I've tried every USB port, the original cable that came with my phone, the cable that came with my HTC 10, and 2 other cables I had lying around. I also tried factory resetting my phone. None of this worked.
I've tried a few combinations of uninstalling and reinstalling the USB drivers.
I don't have another computer I can use to test with.
Same problem here, can t connect my phone to pc anymore. It worked when i both the phone for 1 week or so and now... nothing. The sound when you connect the cable to the laptop is gone and also the allow and / deny notification you get on your phone.
In downloading mode odin sees the phone and the laptop is makeing the sound.
Whenever you connected your device to the computer, was the USB computer connection on Media Device (MTP)? If it's not on MTP then the computer may not recognize the phone at all.
I have same problem with my S9+ .. I try to install some update to Windows 10 (MTP Drivers) and nothing...
In dawnload mode, also ...don't recognize
This may or may not help, is Bixby updated and configured? I never used Bixby, I turned it off and used Nova Launcher and could not connect to the PC no matter what I tried so..... I turned off Nova Launcher, re allowed Bixby, went through the many configuration nonsense and the phone now connects to the PC. When I plug in the cable the phone shows up as another disk drive and if I click on it, I get internal memory and SD Card and can read or write to either. I've no idea why but apparently Bixby is needed to connect the phone to the PC?
I re activated Nova Launcher and it still works so give it a try.
NOTE: Bixby must be allowed to update first.
Hope this helps at least one of you?
