[PATCH] bluetooth hid quirks: mightymouse quirk (cb3fecc2) · Commits · 戴 / test

I have a bugreport that scrollwheel of bluetooth version of apple mightymouse doesn't work. The USB version of mightymouse works, as there is a quirk for handling scrollwheel in hid/usbhid for it. Now that bluetooth git tree is hooked to generic hid layer, it could easily use the quirks which are already present in generic hid parser, hid-input, etc. Below is a simple patch against bluetooth git tree, which adds quirk handling to current bluetooth hidp code, and sets quirk flags for device 0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.
