Hi,
I regret to say I am no USB guru myself; just using it to communicate
with the Gigaset via an undocumented (sigh) interface. The problem is,
the communication sometimes locks; restarting the application does not
help, but restarting the Gigaset does. The communication is pretty
plain; I just call
(*interface)->ReadPipeAsync(interface, 1, buffer, blockValue,
_readPipeAsyncCompletion, ref)
<ellipses>
Generally this works all right; sometimes though it locks reporting an
error e000404f "Pipe has stalled, error needs to be cleared" in the
console log; in the syslog it adds
Would be grateful for an advice what and how to fix,
have you tried
err = (*interface)->ClearPipeStall(interface, fUSBinPipeRef);
and/or check out
