From 5df4eb054fe056ecb15875e812fdadbc47568d7d Mon Sep 17 00:00:00 2001 From: John DeSilva Date: Fri, 5 Sep 2014 11:13:17 -0400 Subject: [PATCH] HID: Add Holtek USB ID 04d9:a0c2 ETEKCITY Scroll 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, added to hid_have_special_driver, and reduced the usage and logical maximums to 0x2fff, consistent with the other mice in the category. Tested on the hardware. Signed-off-by: John C.
