The UAS mode of Thinkplus is reported to fail to work on
several platforms with the following error message:

[   39.702439] xhci_hcd 0000:0c:00.3: ERROR Transfer event for disabled
               endpoint or incorrect stream ring
[   39.702442] xhci_hcd 0000:0c:00.3: @000000026c61f810 00000000 00000000
               1b000000 05038000

Falling back to USB mass storage can solve this problem, so ignore UAS
function of this chip.
