Dear Oliver, Thanks for the information. I have just reviewed the Windows code to understand the driver functionality to be implemented. Windows driver implements queues and queues are requests then processes hen one after the other. In Linux, I read asynchronous can be implemented through aio fops. I will write & test a small scull driver and post back to you.
