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.

You also need entry in hid_have_special_driver[] to make sure that
hid-core doesn't override hid-holtek-mouse.
Could you please fix that and resend? Thanks.
