The Sony Vaio VGX-TP1E multimedia PC has a wireless keyboard with
a touchpad.

The mouse pointer is wrongly declared as constant non-data variable, which make
HID code to completely ignore all the "Pointer" usages.
Fix the report descriptor before it enters the parser to contain touchpad
pointer description that is correctly parsable (declaring data rather than
constant).
