Keyboard and Touchpad not working "USB not recognized"

Hello,

I own a Surface Book 2 (i7 8GB 256GB). Suddenly the keyboard and touchpad stopped working. If I remeber correctly, this was after an update. The keyboard lighting and screen detatch button still function correctly, but the USB Ports don't. You can't type or use the touchpad however.

Every few seconds an error message pops up, reading: "USB not recognized - The last device you connected is malfunctioning"

I tried installing all the new updates, the Surface Diagnostic Tool, forcefully shutting down but nothing worked. Then i wiped the PC clean and installed a fresh Windows Version. Sadly this also did not bring forth any results.

I suspect this is a software issue, because back in 2018 some users reported similar problems after installing an update. Then the fix was removing said update, but for me it didn't work either.

Thank you!

    Is there somebody who could help me?

    I also checked the USB drivers via device manager. Reinstalling them didn't help either.

    Furthermore, I am not sure if it was right that this post has been moved to USB-C. The problem is not with some adapter but with all the built in ports and of course touchpad and keyboard, since they are also wired per USB through the Surface Connector.
