Comment 50 for bug 6602

In Edgy the rules are already like Marcus suggested:

SYSFS{bInterfaceClass}=="06", SYSFS{bInterfaceSubClass}=="01", SYSFS{bInterfaceProtocol}=="01", MODE="0660", GROUP="plugdev"

But they don't seem to work. udev is 0.93. OTOH the script check_ptp_camera apparently works, and consists of this one-liner:
grep -q -F 06 /sys/$PHYSDEVPATH/*/bInterfaceClass

Is the problem that udev doesn't match on the interfaces?
