Yes- there is a bug in linux kernel which makes it behave differently
when using the xhci_hcd driver instead of ehci_hcd. The former is used
by USB3 ports (and some USB2 ports).
Late last year, I added a workaround to the sane-backends development
version. Some users have reported that this fixes the issue for them.
Others continue to have problems. Perhaps you could try to build
sane-backends from a git checkout, and see if it works for you?
