The report descriptor for the HOLTEK USB ID 04d9:a0c2 (ETEKCITY Scroll
T-140 Gaming Mouse) is set to a very large amount of consumer usages
(2^16), exceeding HID_MAX_USAGES. Added id, bindings and comments for
the mouse, and reduced the usage and logical maximums to 0x2fff,
consistent with the other mice in the category.
Tested on the hardware.
