[Q] USB connection fails on 3 different PCs

I wanted to root my phone and flash a costum rom... unfortunately my DHD (2.2.1) is T-Mobile branded, so i had to create a goldcard in order to downgrade from 1.75.111.2 to 1.32. When it came to temproot it manually with cmd i had to plug my DHD into my PC in load only mode, usb debugging activated.
I knew already that my DHD wont recognize my PC or the other way round (i somehow broke it when i deleted the htcsync drivers.exe from my sd card), but i thought maybe it would somehow work in usb debugging mode.
Well, it didnt(phone not found).
i then focused on repairing my usb connection, so i tried it on 2 other pcs (mine is w7, the other ones are xp and win7) but it all failed
(xp asked for drivers, which i installed directly from htc.com today(on all pcs(plus i removed and reinstalled them all properly))/win7 did nothing/mine said that it fails to connect and that i should use a usb 2.0 port(well all ports are usb 2.0, i also tried usb3.0))
evertime i plugged my DHD in i was asked which connection i want to use, none worked, i also restarted my phone several times (usb connected and without) when i type in #7284# (or *#7284# i tried both) it says: connection failure or invalid mmi code
Finally i resetted my phone and did it all again! But it wont work!
please help me!

Hi...It looks like a driver issue...
If your drivers are installed correctly, in your win-7 Device manager it will show DHD.
I would suggest to Re-install HTC Sync from HTC website - Run it again and give it a try

doesnt work either.... win7 says the device does not run properly, my phone does nothin unusual...
i wonder if htc could fix the issue... this would be my last option
however i believe in you guys at xda!

how did you reset your phone?
Did you install the android SDK? Does adb recognize your phone? (run "adb devices", if your device is listed, everything should be fine)
On my win7-machine, the HTC-Software gives me an error message (along the lines of "phone doesn't respond" or something like that) but adb works nonetheless.

thank you for your answer but im afraid it didnt work... i installed the usb driver pack on sdk but i couldnt find it under sdk/usb driver..., however i found some files -> android/android-sdk/extras/google/usbdriver/amd64 -> usbdrivercoinstall2.dll... i tried to install this driver in hardware manager, and i tried to install an adb.exe which i found in my downgrade folder as a driver. but win7 said no driver installation is necessary the "best" drivers are already installed (win7 aint gonna install anything)
also my dhd is found under unkown device, -this device is deactivated because it made errors- "Dieses Gerät wurde angehalten, weil es Fehler gemeldet hat. (Code 43)"
well i deinstalled it and searched for new hardware, he now says the drivers are installed properly please restart however i neither see my sd card nor my devices name (instead unkown device with this little yellow triangle)
btw. for reset i used my android reset (settings -> sdcard -> reset)

It is normal, the HTC Sync turns on the USB debug?

Have the same issue. My DHD can be connected to the PC no other way than charge mode, no matter is usb debugging turned on or off. Tried 2 PCs with W7 and 1 PC with Ubuntu 10.04. This trouble appeared several days ago. Wipe didn't help. Thinking of re-installing firmware, but it seems like hardware problem. An engineer in our service center said it might be motherboard malfunction.
Some ways of solving this problem are described here: http://goo.gl/2eMcP But none of those solutions helped me. If anyone can help, please advise.
UPD: re-installing the firmware had no success - connection with PC failed. 95% hardware problem, will take it to service center.

Guys I know it's a stupid advice, but I had same problems (suddenly my connection with pc didn't work anymore): did you try to change usb cable?

tried 3 cables and 3 PCs

i just found a solution for me : i tried a forth pc (win7) freshly installed htcsync + android sdk + !downloaded! (not properly installed) adb drivers (which i surprisingly did not need) well i plugged my DHD in and he installed all drivers, but never asked for an adb driver. instead he had problems installing 7 different bluetooth drivers for my DHD (???)^^
it just worked for me this way (also worked for debugging mode + load only mode (for radio s-off/hboot s-off))
:|)
well it's not exactly a permanent solution just a temporal way to root my phone, but in worst case i think its nessesary to reinstall win7 on your pc....

[Q] Still Can't connect to Win7 PC (driver issues?)

Hi there.
I picked up a refurbed Incredible 2 (running 2.3.4) and am trying to get it to connect to PC so I can move files across between the PC and either internal memory and/or microSD cards. I'm having no luck on Windows 7.
I changed the Default Connection Type from Charge Only to Media Sync / Disk Drive / HTC Sync (after installing the HTC Sync software - NOT the HTC Sync Manager, which apparently only supports the newer phones) to no avail. I've tried them all, and they all have the same issue. I've done this both with and without USB debugging checked, and with "Unknown Sources" ("allow installation of non-Market apps") checked. I've also tried uninstalling Sync, installing Sync Manager, trying again (no change), and then reversing it (uninstalling Manager, and reinstalling Sync) - again, no change. Sync does not see the phone while connected and in "HTC Sync" mode via the Default Connection Type (or anything else).
When I plug the phone in to the PC the PC shows a "USB Device not recognized" and sometimes I will get a "Driver did not install successfully" message. Device Manager is showing one Unknown Device with a "!" issue under the USB controllers category I'm assuming is the problem. There is also nothing showing up under the Disk Drives category in my Device Manager other than my hard disk, even though some of the guides I'm looking at say I should have something related to the phone in there.
I've tried connecting it with 2 different USB cables, just in case the one that came with it was not fully functional. I've used the second cable for data transfer in the past, so it should work. No difference.
I've restarted several times, with and without the microSD card installed. I've tried unmounting and remounting the card as well, no difference.
Am I missing some kind of Win7 drivers for the Incredible 2 that are not installed automatically and/or with the HTC Sync install? I've seen some references and links to HTC drivers that are apparently not on the HTC site, but I am very leery of downloading an .EXE from a random website and just installing it to see if it works. I'd think if this was necessary, it would be on the HTC site.
Anyone know what gives here? I can't think of anything else to try.
Am I a complete newb here, or is this potentially an issue with the refurb'ed phone?
Thank you very much for any assistance!

I use the driver linked on the revolutionary.io site (http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe) and I have never had an issue.

update
Hi there.
I attempted this, but still no change. Do you know where this installs the drivers to, so I might try to manually point the Device Manager "Unknown Device" to them?
When I try to update the driver via Device Manager, however, it is telling me the following:
"Windows encountered a problem installing the driver software for your device.
windows found driver software for your device but encountered an error while attempting to install it.
'Unknown Device'
Windows has stopped this device because it has reported problems (Code 43)"
Thank you for any further assistance or ideas.

Doesn't matter where you place them but you'll need to go to control panel/system/device manager find the device with the issue and select update driver.... Then it should be recognized

OP - do you have any other USB device drivers for other smartphone(s) installed on your PC? If so, uninstall all of them and reboot it clean.
Assumed that you are running VZW stock software - phone isn't rooted ?
Is your HTC Installer running this version - 3.0.0.007 - that's mine (have it running on W7 Pro and Ultimate on desktop & 2 laptop, no problems for me - I also have it running Win 8.
Uninstall HTC Installer & reboot - without connecting the phone. Turn off firewall & antivirus on your PC temporary, reconnect the phone & follow the prompts to reinstall HTC drivers. Once it's done, disconnect the phone & power down the computer.
Restart the PC and then reconnect the DI2 to it, hopefully - it will recognize the phone and allow you to connect & recognize the mSD card for data transfer, etc.
Please post any specific error messages as you see them. Good luck.

A common cause of "unrecognized USB device" is a bad cable. Try another. Or, try a different USB port on your PC.

fastboot not detecting phone

I have an HTC Incredible 4G LTE. I underwent the process detailed here to unlock the bootloader.
When i got the HTCDev website, i ran a fastboot command and it just says <waiting for device>. I tried to detect the device with adb devices, and fastboot devices, but with no success. the THC Sync manager is not installed. HTC drivers should be installed. I am plugged into a USB 2.0 port, the same one used through out the process (i even tried the other one).
I am at a loss as to what is happening. I do know that the device manager sees my phone, and shows the drivers as the latest version. It does give this message:
This device cannot start. (Code 10)
A request for the USB BOS descriptor failed.

The device manager is listing the driver as version 2.0.7.3.
EDIT: Was able to get driver updated to 2.0.7.18
Also, when connected to the computer normally an orange light shows near the speaker. I wasn't concerned at first as I know the Android OS is not actually up and running on the phone, but do wonder if it doesn't indicated a problem.
Another note, I am running Windows 8.
EDIT 2: More research has yielded the following "Android Bootloader Interface". Every reference installing this from the usb_driver in the ../extra/google/usb_driver folder. When I attempt to do so from the device manager Have Disk ui I receive the following error
The folder you specified doesn't contain a compatible software driver for your
device. If the folder contains a driver, make sure it is designer to work with
Windows for x64-based systems.

EDIT 3: Removed entire android sdk, redownloaded and installed. Removed all HTC software and drivers. Booted phone into fastboot, and windows detected an "Android 1.0" device, installed the Android Bootloader Interface driver from the google usb_driver successfully. However, fastboot devices still does not detect the phone, and device manager still shows code 10.
As of now:
No HTC Sync, or HTC Driver
phone booted into fastboot, phone displays "FASTBOOT USB"
phone is set to usb debug
phone is connected to pc with good cable to a usb 2.0 port
I have:
rebooted pc, re-installed drivers, changed usb cords, changed usb ports, even tried a usb 3.0 port, i have tried some generic fixes for code 10 errors, and completely run out of ideas
EDIT 4: After using a different computer running Windows 7 I was able to complete the process, however, i would very much like toresolve the issue with my own PC, as the Win7 laptop is not mine. I utilized the adb/fastboot/winapi files from my Win8 machine. Win7 automatically found HTC drivers (2.0.7.18) and everything seemed to work just fine. Any ideas?

Help usb and fastboot not reconized

I am getting a Unknown usb device (device descriptor request failed) It keep telling me usb device not recognized while being plugged it. I have tried several things
1. another windows 10 computer worked the first time then same error as a laptop.
2. unintalled the driver and rebooted.
3. also used multiple usb ports
cant find anything after searching
pixel 2 xl 8.0 September update
rooted lastest magisk 15.3
latest twrp installed
stock kernel
recently a fresh install a few days ago because i got it to work somehow but not anymore what do i do?
adb, fastboot, and storage cannot be accessed

Try these steps:
-uninstall previous version of SDK tools from PC
-download latest SDK Tools from HERE
-have a USB 2.0 cable available
-follow these steps to verify connectivity
see if these things help
Unless there is a specific reason you're still on Sept 8.0, I'd take this chance and upgrade to lasts 8.1 factory image.

I'm just spitballing here but....
With phone plugged in, on your pc, under device manage. When you open it up do you see unknown android device? That driver may need to be updated. Also, USB debugging is on, and the option to transfer files? Is your SDK platform-tools up to date?

I forgot to mention downloaded the platform tool for both computers. I never updated because i had root and nothing new was that interested enough to start all over. I followed the steps and nothing usb debugging is on. In device manager its says Unknown usb device (device descriptor request failed). I cant transfer files or anything. I tried updating to the google driver but it said it wasnt compatible.

I haven't seen it with this phone yet, but try changing the USB mode on your phone from the notification; I've had a few phones that refuse to work in specific modes.

Have you tried a different USB-C-A cable just for the heck of it. May have to factory reset and see if that solves it.

So your driver is messed up. Did you use the driver below?

Sent from my taimen using XDA Labs

It won't let me install the driver I get some kind of error when selecting it. I was able to get it to work after plugging it in and out. Now that I updated to 8.1 everything was fine untill I got home. Now it's doing it again. I tried 2 different cables restarted my computer and laptop and can't figure out why it was working fine before without doing anything different.

Try this:
1. Go to C:\Windows\INF
2. Find the file "wpdmtp.inf"
3. Right click the file and click 'Install'
4. Once that is done, simply plug your phone and it should work.

I could not get gaps so I used Android flash tool to attempt to go back stock and it downloaded and flashed it but it is now stuck in loop, I reboot to recovery and it’s stock now and it will not be recognized by adb or fast boot,!0plesase help

Cannot install USB drivers for Razer phone on Win10

Howdy,
I'm trying to get my phone unlocked and rooted. As the first step, of course, I'm trying to get the Google USB drivers to install, but I simply can't. I feel like I'm the only person having this issue, though because I cannot find a solution... The steps I'm following:
Downloaded the latest driver zip from Google
Open Device Manager
Expand Portable Devices
Right-click on the Phone entry (notice, that's the entry, "Phone". Not Razer.)
Choose Update Drivers
Browse my way to the drivers folder and click Next.
Windows then returns immediately "The best drivers for your device are already installed", and shows that it's an MTP USB Device.
I noticed that under USB devices, there's an ADB Interface device listed, and I get the same results when I try to update that, too (excepting it says it's an "ADB Interface" device, of course). I have tried uninstalling both devices to get the drivers to install, but no such. I've rebooted both phone and computer as well.
On the phone, USB Debugging is turned on, and USB mode is set to MTP file transfer.
Please help!

Figured it out...

In case anyone else is seeing the same issues, I wanted to put my resolution up: I'd been trying to install the drivers with the Razer booted. On a whim, I rebooted it into Download Mode using "adb reboot bootloader". Once there, I had an Android Device listed in Device Manager. I ran the driver update wizard, and installed the "USB ADB Interface" option from the choices presented. I was then able to run the OEM unlock command and received the confirmation prompt on the Razer. Yay!
Now, since it's been so long, I've got to re-back-up everything so I can actually do this thing. LOL

Here's the PDF from Razer's how to install a factory image over PC guide. It explains how to do it all
