When the device stalls, clear it and retry; if it keeps failing too often, reset the device. This specially happens when running on virtual machines; the real hardware doesn't seem to trip on stalls too much, except for a few reports in the mailing list (still to be confirmed this is the cause, although it seems likely. NOTE: it is not clear if the URB has to be resubmitted fully or start only at the offset of the first transaction sent. Can't find documentation to clarify one end or the other. Tests that just resubmit the whole URB seemed to work in my environment. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com> |
