-18 = -EXDEV
Documentation/usb/error-codes.txt says:
| -EOVERFLOW (*) The amount of data returned by the endpoint was
| greater than either the max packet size of the
| endpoint or the remaining buffer size. "Babble".
| -EPROTO (*, **) a) bitstuff error
| b) no response packet received within the
| prescribed bus turn-around time
| c) unknown USB error
| -EXDEV ISO transfer only partially completed
| look at individual frame status for details
| (*) Error codes like -EPROTO, -EILSEQ and -EOVERFLOW normally indicate
| hardware problems such as bad devices (including firmware) or cables.
