@ -76,6 +76,13 @@ A transfer's actual_length may be positive even when an error has been
reported. That's because transfers often involve several packets, so that
one or more packets could finish before an error stops further endpoint I/O.
For isochronous URBs, the urb status value is non-zero only if the URB is
unlinked, the device is removed, the host controller is disabled, or the total
transferred length is less than the requested length and the URB_SHORT_NOT_OK
flag is set. Completion handlers for isochronous URBs should only see
urb->status set to zero, -ENOENT, -ECONNRESET, -ESHUTDOWN, or -EREMOTEIO.
Individual frame descriptor status fields may report more status codes.
