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?
