  usb-quirks: Add reset-resume quirk for MS Wireless Laser Mouse 6000
  usb: xhci: rework root port wake bits if controller isn't allowed to wakeup
  USB: xhci: Reset a halted endpoint immediately when we encounter a stall.
  Revert "xhci: clear root port wake on bits if controller isn't wake-up capable"
  USB: xhci: don't start a halted endpoint before its new dequeue is set
  USB: uas: Add no-uas quirk for Hitachi usb-3 enclosures 4971:1012
  USB: ssu100: fix overrun-error reporting
  USB: keyspan: fix overrun-error reporting
  USB: keyspan: fix tty line-status reporting
  usb: serial: ftdi_sio: add PIDs for Matrix Orbital products
  usb: dwc3: ep0: fix for dead code
  USB: serial: cp210x: add IDs for CEL MeshConnect USB Stick
