Description Martey Dodoo 2009-04-25 20:08:56 UTC

When I use my wireless Mighty Mouse to horizontal scroll, it is inverted (moving the ball right scrolls left, and vice versa). I believe this is because the APPLE_INVERT_HWHEEL quirk is added to the wireless Mighty Mouse when it does not need to be.

Modified hid files por apple mighty mouse bluetooth

removes the quirk that inverts horizontal scroll and a small polish to how the product ID is referenced

How may I propose to fix the mighty mouse with this patched files I just uploaded zipped???

Do I have to make a diff or something?

Maybe submitting the patch somewhere else?

Also, adding another mighty mouse with product ID 0x1000 might be necessary. But I cannot tell for sure cause I don't have such mouse to do some testing. (It appears that the horizontal scroll was inverted to make that OTHER mighty mouse trackball work correctly, with the wrong product ID though)

Comment 3 Jiri Kosina 2009-06-17 13:26:57 UTC

The inverted wheel problem should be fixed by commit fa047e4f6fa63a6e9d0ae4d7749538830d14a343, if not, please reopen.

With 0x1000 the problem is slightly different -- the scrollwheel doesn't seem to be present at all, and a different quirk (yet unknown) will be needed.

As reported at http://www.spinics.net/lists/linux-input/msg04037.html, commit fa047e4f6fa63a6e9d0ae4d7749538830d14a343 ended up removing Mighty Mouse support. The patch in that email message has restored it, and fixed the scrolling issue.
