[Note] Handle detection does not seem possible in UMDF

[Ryochan7]

It looks like my idea to keep track of open file handles is not feasible in UMDF. At least with the HID minidriver approach, the EvDeviceFileCreate callback cannot be overwritten in a driver. That does not seem to be the case with a similar approach in a KMDF driver.

I guess I will not worry about the auto reset at the driver level idea. Needs to be handled at the client level.

The more I play around with tweaking this driver, the more I feel like I am easily hitting the limits of what is capable in UMDF. Kernel mode drivers are more practical. Too bad Microsoft gatekeeps so heavily. I need to attempt to reapply for the hardware program again.
