The UAS mode of Norelsys NS1068(X) is reported to fail to work on several platforms with the following error message: xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8 xhci-hcd xhci-hcd.0.auto: @00000000bf04a400 00000000 00000000 1b000000 01098001 And when trying to mount a partition on the disk the disk will disconnect from the USB controller, then after re-connecting the device will be offlined and not working at all. Falling back to USB mass storage can solve this problem, so ignore UAS function of this chip.
