Description Helmut Jarausch 2021-11-03 17:45:46 UTC 
gentoo-sources-5.15.0 fails to recognize my USB mouse.
Rebooting to 5.14.15 doesn't have this problem without any other change (cables,...)

Here some relevant diffs from dmesg output:
iommu: Default domain type: Translated 	          iommu: Default domain type: Translated

Furthermore 5.15.0 hangs on powerdown while trying to (re)mount ro

Sometimes some rebooting solves the USB mouse problem temporarily.

This is on an AMD 64 machine.

Can you do a bisect bewteen 5.14.15 and 5.15.0 ? 
One problem at a time, though.
Comment 2 Mike Pagano gentoo-dev 2021-11-19 20:17:07 UTC 
Can you try with 5.15.3 ? Can you try a different USB port ?
Comment 3 Helmut Jarausch 2021-11-20 12:08:42 UTC 
My USB mouse is connected to my LG monitor which in turn is connected to my PCs USB-C port.
This worked well in 5.14.x even if CONFIG_TYPEC wasn't set in the kernel configuration.

Now, I have set 
CONFIG_TYPEC=y
CONFIG_USB_ROLE_SWITCH=m

which gives a working 5.15.3 kernel
