Hi Paul,
Did you see my messages about this a few weeks ago?
http://thread.gmane.org/gmane.linux.kernel.input/4984
I didn't post a patch because I believe that this stuff has all moved as a
result of Jiri Slaby's patch "HID: move apple quirks" posted to linux-input
on 2008-05-16. One of us should prepare a patch against the tree after
that patch.
Does HID_QUIRK_APPLE_NUMLOCK_EMULATION do anything useful on these keyboards?
I have not enabled it.
Do you know what happens if you have a USB bluetooth dongle with HID proxy
mode? My assumption was that the vendor and product IDs from the keyboard
would then appear to the kernel as USB IDs. If this is true, then you should
keep the existing entries for these devices in the USB quirks tables. Does
anyone know if HID proxy dongles actually do this? In any case, leaving
the existing entries in the USB quirks table can't do any harm.
I wrote this up at http://chezphil.org/apple-alu-bluetooth-kb-linux/ and I'll
just post that URL again to help the search engines...
Cheers,
Phil.
