Things have changed with 4.9 kernel. The thumbdrive is no longer getting
recognized as high-speed and super-speed device both at the same time.
Instead it's getting recognized as high-speed device only and then just
as before the host controller gets halted.
[ 4.558036] usb 3-1: new high-speed USB device number 2 using xhci-hcd
[ 14.638023] xhci-hcd xhci-hcd.1.auto: xHCI host not responding to
stop endpoint command.
[ 14.638073] xhci-hcd xhci-hcd.1.auto: Assuming host is dying, halting
host.
[ 14.671970] xhci-hcd xhci-hcd.1.auto: Host not halted after 16000
microseconds.
[ 14.672009] xhci-hcd xhci-hcd.1.auto: Non-responsive xHCI host is not
halting.
[ 14.678091] xhci-hcd xhci-hcd.1.auto: Completing active URBs anyway.
[ 14.685502] xhci-hcd xhci-hcd.1.auto: HC died; cleaning up
[ 14.692118] usb usb4-port1: couldn't allocate usb_device
[ 14.692127] usb usb3-port1: couldn't allocate usb_device
When increasing HUB_ROOT_RESET_TIME to 150ms it just works.
[ 5.359669] usb 4-1: new SuperSpeed USB device number 2 using xhci-hcd
How to fix this properly and without touching timeouts in
drivers/usb/core/hub.c?
Thank you
Thomas
