Hello,
I was wondering what happens if you issue a Read on an interrupt IOUSBPipe,
which returns kIOReturnSuccess, then call Abort on the pipe and Close on the
IOUSBInterface before the callback for the Read has been called? I seem to
get a kernel panic when this happens. Does this count as outstanding I/O
and therefore you shouldn't call Close on the interface? This sequence of
events occurs if I unplug my device without generating any input with it, so
the callback never gets called.
Thanks,
Jessica
