Is the xhci_hcd kernel module (a.k.a. USB 3) used
for the USB port where the scanner is connected to?

See what "lsusb" and "lsusb -t" reports to find out
to what USB bus and port the scanner is connected to and
then to find out what kernel driver (i.e. kernel module)
is used for that USB bus and port.

If "lsusb -t" reports "Driver=xhci_hcd" for the USB bus
and port where the scanner is connected to you are
hit by the current general USB 3 issues in the kernel.
