Whenever i try connecting my htc hero to my laptop via a cable, it just comes up with usb device not recognized, I have windows vista 32 bit, it used to work just fine on 1.5 rom, but I've got villainrom 5.5 and doesnt seem to work. I've tried on other computers aswell and i get the same result.
However I have tried connecting to the computer via fastboot and the device is recognized and installs "My HTC" driver.
Not entirely sure what to do. Any ideas?
Maybe start here,...
HTC Hero trouble synchronizing with PC? Read this...
Its not that sync doesn't work, the usb just isnt recognised at all. But when in fastboot the phone is recognised via usb. But adb doesn't work, so i cant mount the sdcard via usb, i have to do it manually. I don't actually have a clue what is going on
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?
I have tried multiple times to install the USB drivers for my Optimus T (LGP509TN) running CyanogenMod 7.1 (6.5.8). I've tried installing, uninstalling - tried using the LGmobile agent to install... 5 of the 7 install fine but the LGE Android Platform USB modem and the USB Mass Storage Device fail. (see attached image called "usb installation")
When I turn on USB tethering, another USB installation routine runs and fails. (see attached image called "after turning on USB tethering". In Device Manager, I get a bunch of exclamation marks. (see attached image called "Device Manager".
USB storage actually will work - but takes a long time to kick in - and often crashes. Same with USB tethering. I've tried numerous different USB cables so that's not an issue.
Although I have an LGP509TN, I'm not sure if I should be installing LG509 drivers or LGP500 (as I'm running CyanogenMod 7.1 for LGP500). I'm not sure if there actually is a difference between the two. I've tried both and get the same issue.
Any direction would be sincerely appreciated.
Thanks,
Dave
Hi ,
I am also finding same problem. installed cyanogenmod
I took back up in ROm manager but not in recovery mod.
LGE android USB Modem fails to install.
Rest things are installing and working fine.
Help me out if you have found the soultion.
For you what i suggest is.
1. uninstall LG united drivers through control panel.
2. Re install it and turn on USB Debugging mode in your phone and connect it.
Everything will get installed. But not sure of LGE Android USB MOdem. IF you get soultion let me know even
I've tried everything that's been suggested. I've tried many different versions of drivers. Uninstalled, reinstalled.... Sometimes I'm even getting the Blue Screen of Death on my laptop when trying to connect the phone using USB. Wireless tether continues to work flawlessly. It's simply the USB connection that doesn't seem to want to cooperate.
I'm starting to think it might be a hardware issue - except that everything else with the phone works perfectly. I'm also going to buy a couple of new USB cables to try to determine if it might be a faulty cable.
1. Turn on USB Debugging mode
2. Connect USB
3. Then drivers stopped installing, turn off USB Debugging mode, but do not disconnect usb cable.
4. It will install some drivers and says all OK
5. Turn on USB Debugging mode (do not disconnect usb cable), and all drivers will be installed.
This is my method, and it worked for me.
Thanks for the instructions. The challenge I face is that the 2 devices never complete. (See screenshot.) If I close the dialogue, it tells me of the failure. When I switch on USB Debugging, it doesn't connect.

Experiencing similar problems with getting the USB drivers required for native tethering installed successfully. Running Windows 7. A walkthrough of clearing any existing drivers then reinstalling the proper ones might help. I've tried uninstalling via the control panel, system, devices area, but a complete purge/deletion of the drivers might be needed. Any pointers to a proven way to do so would be appreciated.
dude this happens to me week ago
first tell me are you running .32 kernals ??
if yes then flash it once aganin
or use .35 kernals it's best for cm7 series
okay i was going to flash the official ICS for my GS2 then i plugged my phone up and it said "Windows cannot recognize this device" so when i put it in download mode my computer does not even show that its plugged. Heres all what i have already done to solve the issue:
tried 4 different computers
using stock wire & other wires
restarted computer & phone
pulled battery
removed external memory card
uninstalled & re-installed drivers
turned off usb debugging, when i do it says MTP Initialization
wiped system data/cache
and restored from a backup rom to see if it was them rom
any help?
You should try this app.
When I tried to connect my rezound to my desktop PC the PC tells me the usb device is not recognized. It used to work where I can connect to my PC and look through files on my rezound, but it hasn't been working for a while. Does anyone know what the issue is? I tried enabling usb debugging and tried installing HTC sync and used some of the settings in "connect to my PC" section of the settings, but it still doesn't work. What I want to do is backup some files and eventually root and flash for the first time. I currently have an S5, but I want to root and flash on my Rezound. Thanks for any help.
Update: I got it work. I think it may have been a cable or port that wasn't working right as I used a different cable and usb port on my PC
