Subject: Re: [Bug #13935] 2.6.31-rcX breaks Apple MightyMouse (Bluetooth version)

Hi,

I can confirm the reported bug, but for me reverting fa047e4f6fa63a6 is
not sufficient. I have to remove the device id of the mighty mouse from
the hid_blacklist list in drivers/hid/hid-core.c as well, see the patch below.

Concerning the need for the quirks: I think there might be some
dependence on the version of X that is used. If I recall correctly, with
xorg-server-1.3 the quirk "APPLE_INVERT_HWHEEL" was necessary, but this
changed when I switched to xorg-server-1.5.3, where now horizontal
scrolling moves in directions you'd expect from vertical scrolling.
...but I wouldn't bet on my memory regarding things with xorg-server-1.3
since it's been quite some time ago and I never really liked the
horizontal scrolling anyway.

Cheers,
Jan

Subject: [PATCH] HID: commit fa047e4f is incomplete

Commit fa047e4f6fa63a6e9d0ae4d7749538830d14a343 "HID: fix inverted
wheel for bluetooth version of apple mighty mouse" is incomplete. If
we remove Apple MightyMouse (bluetooth version) from the list of
apple_devices in drivers/hid/hid-apple.c we have to remove it from
hid_blacklist in drivers/hid/hid-core.c as well.
