Flutterby™! : Annoyance of the moment

Annoyance of the moment: PyUSB reporting a read timeout with a usb.USBError("No error"). The work-around is

try:
    response = handle.bulkRead(0x81,50)
except usb.USBError, error:
    if error.message != "No error":
        print "Unexpected error:", error
        raise error
