This is a SET_ENCRYPTION request to the HWA. ([WUSB1.0] section 8.5.3.6).
-71 is (according to Documentation/usb/error-codes.txt)
-EPROTO (*, **) a) bitstuff error
b) no response packet received within the
prescribed bus turn-around time
c) unknown USB error
So something is broken in the firmware or hardware of the HWA and it's
probably disconnected -- it's not the device driver doing something wrong.
You'll need to ask a Wisair hardware or firmware engineer for assistance
(assuming the HWA you're using has a Wisair chip).
