Public bug reported: 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? ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1395271 Title: USB 1 and USB 2 scanners fail when connected to USB 3 ports To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1395271/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
