thank you very much for this statement. xhci-hcd is unusable for
many people. On my laptop I can't scan more than one document, the
laptop sometimes immediately wakes up after suspend and after almost
two years all of these issues remain.
I am running kernels with a hacked up pci-quirks.c for months and
scanning documents work, suspend/resume is working, no issues with
USB serials. My job is not related to Linux kernel development so
I would love to go back to a distribution kernel. Please make this
possible. In the end "xhci" appears to be a "supported" driver?
cheers
