Accessing vendor-specific report in HID mouse
You can't get at it from UM. You must use a device lower filter to get it. See
the firefly example.

Subject: [ntdev] Accessing vendor-specific report in HID mouse
When a HID mouse defines a report with vendor-defined usage page in the Generic
Desktop / Mouse top level collection, is there a way to access it from Win32
user mode code?
As far as I know, mouse's TLC device is exclusively opened by the OS and I
cannot open it, and I cannot get WM_INPUT with RAWHID for the device either.
(all I get is WM_INPUT with RAWMOUSE, which doesn't include non-standard
information) So, I guess the answer is no, but I just want to make sure that
I'm not missing anything...
And, before you ask, no, I cannot change the device's HID descriptor.
