Hi Everyone —
First time post/patch to here, so forgive me if I did something wrong. This patch is to fix the OS X HID code to detect mice when they are part of multi-function devices. In particular, I have a Microsoft Optical Mouse with Tilt Wheel that reports back multiple usage/usagePage values, and it’s primary values don’t happen to be generic desktop/mouse.
Thanks!
