If the driver is a clone driver=0D I suspect that we would use the major number returned by the register=0D call. What is the queue locking state of the clone driver and do we=0D need to control this also? =0D =0D Thanks Gary Schumacher =0D SPECIAL NOTICE=0D All information transmitted hereby is intended only for the use of the addressee(s) named above and may contain confidential and privileged information.
