Did you recently update your BIOS?

The reason I ask, is that I ended up with the same problem on my
Thinkpad X1 Carbon 4th Gen a few days ago after updating to the latest
revision (version 1.49 - obviously model specific and irrelevant. The
bios_date is 05/25/2021)


I tried the tricks I know of in an attempt to solve this without a reboot:
 - unloading and reloading the XHCI driver and the complete USB subsystem
 - removing the PCI device from the bus and rescan

Nothing of that helped. This is the log from the problem occured and
with all these attempts to "fix" it:

The reboot after the BIOS update was at Aug  3 19:30:30, so it took at
few hours before the problem appeared.  It was still close enough that I
assume there might be a relation, given that BIOS updates is a very rare
event for me...


So I took the generic advise I never follow: Reloading BIOS default
settings.

This might have solved the issue.  I have not seen it since.  But as you
see: It's only been a few days, so that could be just a co-incidence.

But pease try. This will give us more data either it helps or not.
