[Q] Driver problems

I have an HTC One M8 by T-Mobile, running the latest firmware, unlocked, rooted and on Android 5.0 Lollipop with the stock recovery. (I put the stock recovery back on because I had no need for the custom at the time and charging would bring me through the recovery and be real annoying).
I had no problem doing all of this but now (a few weeks later) I need to get the custom recovery back on in order to flash a new ROM.
Problem is, I'm connecting my phone to my computer and I can't get ADB to connect, HTC Sync Manager shows there's no device connected and windows explorer only shows a new CD Drive connected and mounted on (F that doesn't work and does not act as a storage platform for my phone.
What I have tried:
Disabling USB Debugging
Restarting Phone
Re-enabling USB Debugging
Un-installing HTC Sync Manager
Force installing "androidusb.INF"
uninstalling HTC Sync Manager, unplugging phone, disabling usb debugging, turning off phone and then going back through again, installing, plugging in turning on and enabling.
Really puzzled here, need to connect to ADB to flash custom recovery to go back to my stock ROM.

Try using the generic Android MTP drivers in Device manager. Of course you could also check all the basics as well.
Try a different port or a different cable. Try to kill the adb server and restart it. Can also try revoking the USB permissions and accepting again when prompted on the device.
Though you don't really need adb to flash the recovery, it needs to work in Fastboot mode. ADB will only work in a running OS or in a recovery, fastboot of course from fastboot mode, which is what you'll need in order to flash the recovery. You won't need USB debugging enabled for it either.
Try some of the stuff above, especially if maybe it's a cable or port issue.

I realize you may find a solution before even considering the option below ⬇

If you have an extra rooted device and get the cable coming you will never have to worry about troubleshooting drivers again considering after an ruu or a conversion you will go through the possible issues of drivers more than once
I've changed my CID,MID,flashed recovery with this method.
Being S-OFF I've not needed to try an ruu through ruu mode but would guarantee it will do the job

adb/fastboot not working

I finally got around to trying to install a custom recovery and root my HTC M8 (Verizon, KitKat 4.4.4).
I had previously unlocked my phone with SunShine - and have S-Off.
I tried installing adb/fastboot/drivers downloading from this thread:
http://forum.xda-developers.com/showpost.php?p=48915118
On my phone I turned off fastboot, enabled developer mode, and enabled USB debugging.
I connect my phone, it says USB debugging connected - and my PC (Windows 7) recognized the device.
However, when I try fastboot devices it does not recognize my phone - it returns nothing.
I realized that I had previous versions of adb/fastboot installed on my PC (From HTC Syanc & the WugFresh Nexus toolkit). I uninstalled them and reinstalled the drivers from that link, but still no adb/fastboot.
One thing I noticed is that (unlike the tutorial video on the link) in Device Manager my phone is not recognized under Other devices/ADB interface, but rather appears under Android USB devices / My HTC. I tried following the tutorial and tried to update the driver software, but it was not possible to use the downloaded Google drivers.
I tried unistalling the My HTC driver. The phone then appears for time under Other Devices / Android phone and then it re-installs the My HTC driver.
The PC recognizes it as an MTP/Media Player device, but not as an ASB one.
Any suggestions?
edit: Never mind. Arg, stupid me - I forgot to put the phone into fastboot usb mode.

Yeah....
ADB commands only work in a booted O.S or recovery
FASTBOOT commands only work in the bootloader

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?
https://dl-ssl.google.com//android/repository/latest_usb_driver_windows.zip
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.

This definitely worked for me -- Thanks for posting!

I am having sort of the same problem. I was on Android 11 on my 2xl, rooted with fast boot boot twrp.Img and installed magisk and super super, all latest. 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

Feb 2019 update kills PC usb connection

Strange issue. After applying the Feb 2019 security patch over air, my phone is no longer recognizing when it is plugged into a PC. I plug into my PC and I get a charge symbol on my battery but no pull down option to switch from charging to USB mode. Things I've tried:
1. New Cable although the wife has a Pixel 3 (standard) that works with this cable and computer just fine.
2. Different PC
3. Toggling USB debugging
4. Changing the USB setting in developer mode to transfer
5. When I plug a USB stick into the phone using the USB-C to USB-A adapter, the phone recognizes the stick and I can browse files
6. "Cleaning" the USB-C port
7. Also booted into safe mode (which I would assume should be like a factory reset) but no USB.
8. Switched between USB 3 and USB 2 ports on the PC.
It seems to me that there's a software issue with the Feb update that messed with the usb settings. I called google and they just want me to factory reset my device before they will transfer me to tech support. I'm avoiding that because I don't want to go back through the time/trouble of resetting up my phone. Any tips/tricks I've missed here?

If you have a Google variant with the BL unlocked, flash the factory image with the -w removed from the flash-all batch file. That way, you won't lose data. If you are on the Verizon variant or don't want to unlock you BL, sideload the OTA from stock recovery. See if it cleans up your issue. Also, sounds like you might have a driver issue on your PC. Easier to fix that first if it is the issue.

I have the February update over the air and I had no issues connecting to my Chromebook (crouton) via USB to pull an APK with ADB. I did have to turn USB debugging back on (not sure if I turned it off or if it was turned off from an update) and change the connection type, it was set to charging only.

More info this morning. I have an Android based car stereo that when I plugged my phone into this morning, I did get the USB drop down. So it seems to be a windows 10 problem. I have both a Surface pro 4 and a desktop running windows 10 that are fully up to date that show the same symptoms. I don't know how I'm going to sideload an update if I can't connect it to my computer.
1. What I don't understand is why the Pixel 3 would work and the Pixel 3 XL would not. Same driver set, no?
2. Also, PC with Windows 7 also has same issue.

Try putting the phone into Fastboot mode and use the command "fastboot devices" to see if it is recognized. If it is, then the problem is on the ADB side, which is part of the Android system.
If it can connect via Fastboot, it's less likely to be a driver issue. You can try "adb devices" too with the phone booted to see if it is recognizing it all. May need to toggle through the various connection modes, I believe I used PTP the last time, but not certain.
As for sideloading, you will need the phone to be recognized by either ADB or Fastboot. You can sideload an OTA update from Recovery with a locked bootloader or as @sliding_billy said you can unlock the bootloader and flash the factory image which is done via Fastboot.
I would also verify that you have the latest version of the Android SDK installed just to cover that base.

You don't need to be in file transfer mode to connect via fastboot. Check connection from there after using the combo keys to get into fastboot (power/vol down) for the factory image or one step further into recovery for sideload.

Neither Fastboot devices or ADB devices lists a device. When put in fastboot and recovery, my device manager on either computer does not register that there is a device connected.

Sounds like you have attempted everything... New cable (but rereading I don't see where you tried using a C>A cable instead of a C>C and that definitely needs tried). New computer/port/OS. Direct connect to fastboot. I think you are going to need to backup to the cloud (at least you have a functional device with internet) and factory reset the device.
P.S. I just thought about this, but do you have the current platform tools (ADB/Fastboot)? https://developer.android.com/studio/releases/platform-tools.html

Sadly I don't have a computer with a USB C port. I have been using only cables with C>A. I downloaded the latest platform tools yesterday before trying fastboot/adb. I'm waiting for a call back from Google tier 2 tech support within 72 hours. If anything comes of it, I will report back here.

Good luck!

pixel 2 xl refuses data connection with all computers except one.

Hi so i installed twrp and rooted my pixel with magisk. everything went fine.
saw the sultan kernel decided to flash but my phone does not recognize any computer with any cable as a computer but as a powersource. Adb and fastboot not working on any laptop or desktop (except the desktop on which i unlocked my bootloader and rooted my device) tried to connect over usb (adb fastboot filetransfer) on Linux Windows and MacOs. all unsuccesfull.
dev options is on:
oem unlock toggled
usb debug toggled
phone is running stock rom stock kernel. (Edit: kernel is the sultan kernel on stock rom)
once i connect the phone sees it as a pc pops op usb options then blacks it out because it sees it as a powersource.
whats wrong with it i cant figure it out...

I'm in very much the same situation. I've seen several USB connectivity threads roll through here recently so I'm not sure if anything larger is going on or not. Basically, I always do updates with full factory images w/o wiping. I was able to install the April update (in early April) just fine. I went back in late April to try to use fastboot and couldn't connect via USB for file transfer, ADB, or fastboot. I updated all my platform tools and the Google USB driver which made no difference. I tried on 3-4 Windows 10 desktops/laptops and 1 MacOS laptop. Nothing. I opened a support ticket with Google (and went through extensive troubleshooting steps) which was then escalated. It has been over a week and they have not responded. I even checked back yesterday to make sure it wasn't lost in the shuffle, and I was assured that it was still active and assigned to the proper team.
Just for giggles, I tried connecting to a Win7 desktop w/ only USB 2.0 and the phone immediately connected MTP (we had made this the default USB mode during the troubleshooting process). Since I was still running a modified (root) kernel, I went ahead and tried flashing the stock boot image with fastboot (both slots) and it worked! I figured since I had already wiped the phone for troubleshooting, I would try pushing the entire April image (w/ wipe). It flashed bootloader, radio, and maybe boot image (can't remember), but then lost connectivity when trying to push the system image. Fortunately, the phone booted right back up. Since then, connectivity is possible, but sporadic, on that machine. Being 100% stock, with no other options, I knew the only way to get an entire factory OTA pushed to the phone would be to opt into the beta, install the beta, then opt out, which pushes the latest non-beta and wipes the phone. I did this, but, again, it resolved nothing.
BTW, for me, this issue affects all devices that pass data through the port including USB OTG flash drives and game controllers. It's also not cable specific as I have tried a factory Google USB-A to C cable, factory Google USB-C to C, and several other USB-A to C cables (the ones I always use for ADB and fastboot commands). There does not appear to be any physical damage to the port and I cleaned it extensively with compressed air and a plastic dental pick.
Sorry I don't have a solution at this point, but I wanted to pass on the steps that I have taken.
