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? allan On Tue, May 26, 2015 at 1:03 AM, <[email protected]> wrote: > "m. allan noah" <[email protected]> writes: > >> What else has changed?
