IRP notation: {38k}<-624,468|468-624>(1820,-590,0:1,D:4,S:6,F:6,C:4,1:1,-???)

This is a mouse protocol. The button press info is included in the Device field. The horizontal motion is in the Subdevice field, and the vertical motion is in the OBC field.

The decode interface does not support returning negative Subdevice or OBC. So negative motions are represented by adding 64 to them. The numbers 1 to 31 represent positive motion. The numbers 32 to 63 are each 64 larger than the true negative motion, so 63 represents -1 and 32 represents -32.
