Subject: udev rule for hid2hci and Logitech dongles doesn't work with kernels >= 3.6

Hello,

I've recently noticed that the udev rule for hid2hci with Logitech
dongles doesn't work anymore. The reason is commit
7e97243c2080ecae7129e83635227fdebd4feef6 which changes the class
(subsystem) for those dongles from usb to usbmisc. I've already filed a
bug for Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=877998) but
I thought I should write a note here too, to inform non-Fedora users too.

My suggestion is to use "usb*" instead of "usb" for the subsystem, this
works with all kernels regardless if the subsystem is "usb" or "usbmisc".

Regards,

Alexander

Thanks and sorry for the long lines. I've used to use the comments as
reference (when invoking git commit), but unfortunately they got longer
since they recently got translated (to german) when using LANG != C.

Thanks. The patch has been applied (after fixing up the commit message
to not include the signed-off-by and to have sensible line widths).

With kernel 3.6 (commit 7e97243c2080ecae7129e83635227fdebd4feef6) the class for some
devices (e.g. dongles from Logitech) were changed from usb to usbmisc. As consequence
the udev rule for hid2hci didn't work anymore with kernels >= 3.6.

Changing the subsystem from "usb" to "usb*" matches both "usb" and "usbmisc" and works
with all kernels.
