Lower filter for the trackball device which will spoil some HID descriptors
to make the device no more a mouse + register a special device interface for
it.
Then access this HID device from user mode HID API (open it by using a
device interface).

I have a mouse and a trackball on my pc. I would like the mouse to
act as normal mouse that controls the cursor. I would like the
trackball to act as a separate device which does not act like a
mouse. Right now, when I plug both in, I get two mice.
The trackball uses HID-compliant mouse driver in the device manager.
I was hoping to write a new driver and install it instead of the HID-
compliant driver. I could then use the new driver in my application
to simply read delta x and y from the trackball.
Could anyone give me some ideas on this? Is there any similar source
code that I could modify?
I open to other methods too. I examined using Raw input but ran into
so roadblocks.
