I'm having an issue where my HTC Thunderbolt is not recognized by my PC 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. When i drag the notification bar down, there is nothing there.
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.
Manually telling the system where the drivers are (Windows says the drivers are not compatible with my device, even though they work for another htc thunderbolt).
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.
Resetting to factory settings.
OS: Windows 7 x64
Note: I tried plugging it into a laptop with Windows XP and everything was normal here.
Is there anyone out there that can help?
Thank you for any information you may provide.
have same problem. did you figure it out?
Well friends the problem is this
My android version is 6.0 and the system version is 24.81.3_titan and I'm trying to do a bootloader to get root access on the device.
> I can't connect it by the USB cable on my windows 7 to transfer files using mtp, I already tried on the linux system deepin and also it is not possible.
>I tested on all computer ports, three different types of usb cable and on two different computers and they didn't recognize the cell phone. it only charges the battery.
>I tested another cell phone, moto max, with the same usb cables and it worked correctly.
I think it may be the version of the system or android that are causing these problems, but I can't do a downgrade because I can't connect it to a computer.
Note 4 Not Recognized by Two PCs
Hello Folks,
I have a Note 4 that I plan to install TWRP then a custom ROM on. Both Windows 10 & Linux Mint 20 do not recognize the phone. I enabled developers options, then enabled USB debugging. I first noticed this when I tried to copy the TWRP.tar file via Odin. The device doesn't show up.
This is allegedly a brand new phone.
There is no popup dialog box on the device when I plug it into either computer. The battery icon up in the tray of the device does have a charging sign, yet no option for file transfer.
However, When I connect a different Note 4 to either computer, it registers fine. In Thunar File Manager on the Linux PC there is a connection icon for the other Note 4 that says, Samsung Galaxy. Also, on that device itself there's a dialog box that pops up & asks for a file transfer. So this other device fine.
So, it seems both computers are OK. The problem is with the new phone. I've tried different USB cables & get the same issue. I've enabled & disabled the developer options & USB debugging & rebooted the device, & same thing. I've also tried a factory reset, that doesn't fix it.
When I search the internet for this issue the only things I've found are reports on swapping USB cables & making sure that USB Debugging is enabled.
I read this post about the same issue. So this might be the problem. Yet, I thought I'd post this anyway in case others have some ideas.
Any suggestions would be appreciated.
Thanks
My phone is not recognized by either my home or work pcs. I've googled and did the basics - enabled usb debugging, preferences set to file transfer. I've never had this problem with a phone before.
It will connect to a usb stick via adaptor so I can transfer files with a multi-step process. This is a pain.

That's strange, either your port is damaged or you don't have drivers installed. I've heard if this happening on Windows 11, never had a problem on Linux

Do you have the latest USB drivers installed?
Get the Google USB Driver | Android Studio | Android Developers
The Google USB Driver is required to perform adb debugging on Windows with Google devices.
developer.android.com
The drivers are installed. My home pc is what I used to unlock/root the phone.
When I look at Show Hidden Icons -> Safely Remove Hardware and Eject Media, there is an option to remove Pixel 6. Yet it doesn't display under File Explorer or XYplorer.
If I start up my Arch (linux) vm with VMware Workstation Pro under Removeable Devices there is an entry for Google Pixel 6 with the option to Connect (Disconnect from Host). The contents can be under Arch.
Have you tried different cables & different ports? Sometimes the cable is the problem for me.
Different cables/ports had no effect.
I've got the same issue, what's weird is I can move files with ADB but can't in Windows.
If you figure anything out please hit this back up?
First make sure you have a good usb cable.
Some cables are only made for charging.
Second install the USB drivers from Google.
If you can transfer files, but can not use ADB/Fastboot, then it is a driver issue.

Cables/drivers are good. ADB/fastboot work fine it's the transferring of file/recognision of device in windows explorer that is the issue.

Switching from charging mode to file transfer mode in the Connected devices/USB menu should give you access to Android's internal storage from Windows. USB debugging or other Dev options aren't necessary.
I had this same problem. Connecting to pc would show connection options but they were all greyed out and the phone would only charge. I couldn't find any option in the standard settings to change this.
Eventually I found 'default usb configuration' in dev options. Default was set to 'charge only'. You can sort it from there.
edit to add: although re-reading op you may have tried this already.
I solved mine by setting to PTP mode then the PC started to recognize the phone connected

It's the stupid Windows drivers. There is an .inf file you need to either edit or delete but I forgot which. Might be wpdmtp.inf in the windows directory, right click and install. You might have to uninstall the driver in device manager first, the one with the exclamation mark if it's there. Sorry it's been about 3 or 4 years since I have done this but it's most likely a driver issue.

I'm checking this on my work pc. It gives me access to DCIM and Pictures folders only. Which give me something to work with at least.

I agree about drivers, that they're either corrupted or incomplete. What's going on in Windows Device Manager when the phone is in a certain state?
During normal operation I assume the general purpose driver is always visible.
Device Manager > Portable Devices > Pixel 6
In fastboot mode with USB debugging enabled, is this driver showing up?
Device Manager > Android Device > Android Bootloader Interface
While Android is running with USB debugging enabled, do you see an ADB driver (the daemon may need to be started)?
Device Manager > Android Device > Android Composite ADB Interface
Hello! I have a (12+256) Motorola Edge+ 2020 in Pakistan. I bought it last September. Everything works great, except that it won't connect to my computer. I have tried changing the default USB connection to File Transfer but it does nothing. The normal "Connected Devices > USB preferences" window is inactive and only accessible by search which doesn't do anything as well. I have tried using Moto tools to update computer drivers and the "Device Help" to access files. The Device Help WiFi route works fine but won't connect through USB. Changed cables, tried on different computers.
