From 212da74da783ba9d4459799f4aaecd5de217a312 Mon Sep 17 00:00:00 2001 From: Josenivaldo Benito Junior Date: Tue, 10 Apr 2012 19:29:04 -0300 Subject: [PATCH] HID: Aureal Remote Control Device Driver Devices like Aureal Cy se W-01RN USB_V3.1 and some derived hardware have a bogus HID Report Descriptor. According to that report descriptor, the maximum logical value for key events is 1 and not 101 (101 keys). This quirk fixes this wrong Report Descriptor.
