Dear Dmitry:
A user filed a bug here which seems to indicate that hid lacks needed
exclusions for Apple pointers:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=208721
Do you think we should be adding QUIRK_IGNORE for these?
Perhaps conditional on CONFIG_USB_APPLETOUCH?
We used to have those IGNORE quirks for Wacom, but then started to ignore
all Wacoms. We seem to be not at that point with Apple yet, and also they
have varying vendor IDs.
Cheers,
-- Pete

Yes, I think we should.

No, I think we should just do that unconditionally and have users select
appletouch driver.

Ping Cheng swore that Wacom never produced HID-compiant device and that
it would be easier for her if we blacklisted Wacom as vendor in HID...

The reporter sent /proc/bus/usb/devices, and the situation seems
clearer now. Perhaps this explains why authors of appletouch didn't
add exclusions themselves.
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 4 Spd=12 MxCh= 0

I: If#= 1 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=01 Prot=02 Driver=appletouch
E: Ad=81(I) Atr=03(Int.) MxPS= 64 Ivl=8ms

E: Ad=84(I) Atr=03(Int.) MxPS= 1 Ivl=8ms
Since it's a multi-interface device, it can't be blacklisted by the
existing quirk bits, can it?
