Is this a good idea?

Subject: Bug#501503: udev: Griffin Powermate USB knob doesn't get
/dev/input/by-id|path links
X-Mailer: reportbug 3.29.3
Package: udev
Version: 0.103-1
Severity: normal
Hi,
I have a Griffin Powermate, which is a USB "knob" that can be used as
e.g. a volume control, for scrolling through video/audio, etc. No
/dev/input/by-* links are created for it. This is because
persistent-input.rules only sets ENV{ID_CLASS} for keyboards and mice
when it recognises them from their ATTRS{bInterfaceProtocol}. This
device has ATTRS{bInterfaceProtocol}==0. I have added this, to give
it class "misc"; I'm not sure if there is an official USB-spec-defined
meaning for protocol==0 that I should be using:
SUBSYSTEMS=="usb", \
ATTRS{bInterfaceClass}=="03", ATTRS{bInterfaceProtocol}=="00", \
ENV{ID_CLASS}="misc"
I now get the desired symlinks:
/dev/input/by-id/usb-Griffin_Technology,_Inc._Griffin_PowerMate-event-misc
/dev/input/by-path/pci-0000:00:10.2-usb-0:1:1.0-event-misc
Cheers, Phil.
