From: John DeSilva Date: Fri, 5 Sep 2014 15:13:17 +0000 (-0400) Subject: HID: Add Holtek USB ID 04d9:a0c2 ETEKCITY Scroll X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5df4eb054fe056ecb15875e812fdadbc47568d7d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git 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.
