error, a failure to respond (often caused by
device disconnect), or some other fault.
--ETIMEDOUT (**) No response packet received within the prescribed
+-ETIME (**) No response packet received within the prescribed
bus turn-around time. This error may instead be
reported as -EPROTO or -EILSEQ.
- Note that the synchronous USB message functions
- also use this code to indicate timeout expired
- before the transfer completed.
+-ETIMEDOUT Synchronous USB message functions use this code
+ to indicate timeout expired before the transfer
+ completed, and no other error was reported by HC.
-EPIPE (**) Endpoint stalled. For non-control endpoints,
reset this status with usb_clear_halt().
usb_control_msg():
usb_bulk_msg():
-ETIMEDOUT Timeout expired before the transfer completed.
- In the future this code may change to -ETIME,
- whose definition is a closer match to this sort
- of error.
