I am experiencing the same problem with a brandnew brother DS-740D scanner, when connecting the scanner to a USB3.0 port on a MSI GE63 7RD laptop with Ubuntu 18.04 LTS, mouse and keyboard connected to USB are dead afterwards.
touchpad and keyboard directly on the machine are still working. On Win10 the scanner works. journalctl | grep -7 "controller not responding" Feb 07 14:02:26 machine5 kernel: xhci_hcd 0000:00:14.0: Abort failed to stop command ring: -110 Feb 07 14:02:26 machine5 kernel: xhci_hcd 0000:00:14.0: xHCI host controller not responding, assume dead Feb 07 14:02:26 machine5 kernel: xhci_hcd 0000:00:14.0: HC died; cleaning up Feb 07 14:02:26 machine5 kernel: xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command Feb 07 14:02:26 machine5 kernel: usb 1-3: USB disconnect, device number 2 Feb 07 14:02:26 machine5 kernel: usb 1-3.1: USB disconnect, device number 4 Feb 07 14:02:26 machine5 kernel: usb 1-3.1.3: USB disconnect, device number 7 Feb 07 14:02:26 machine5 kernel: usb 1-3.1.3.1: USB disconnect, device number 10 No "VIA Labs, Inc" USB host devices.
