Title:
  USB 1 and USB 2 scanners fail when connected to USB 3 ports

Status in “sane-backends” package in Ubuntu:
  New

Bug description:
  Plugging a number of USB 1 and USB 2 scanners into the USB 2 port of
  various computers works as expected. Moving the scanners to the USB 3
  port of the same computers causes the scanners to stop working. The
  scanners are recognized by sane-find-scanner, but fail to scan. The
  difference appears to be the USB 2 ports using ehci-pci and the USB 3
  ports using xhci_hcd.

  The problem is becoming more serious as new computers come out with
  only USB 3 ports and no option to disable xhci_hcd in the bios.

  Is there a workaround or fix for this problem?
