 # Symlink the raw HID device (not the baked HID device) of a Thing blink(1),
 # aka USB vendor:product id 27b8:01ed (cute product id!), using its reported
 # serial number as /dev/blink/$serial.  Also set the mode and group to allow
 # access.
 #
 # This rule matches properties of two udev devices in the device tree:
 #
 #   1. the raw HID device with the SUBSYSTEM condition, and
 #   2. the USB parent device (but *not* the baked HID device in between) with
 #      all the other conditions.
 #
 # udev rules support matching up to two devices: the device you're targeting
 # and up to *one* of its parents.  See more properties you can match with, e.g.
 # `udevadm info --attribute-walk /dev/hidraw1`.
 #
 # For lots of other details on how rules work, see udev(7).
 #
 # Hope this helps!
