-## This file sets up a few things for selected Kaleidoscope-powered keyboards:
-## - We first symlink the device to a more friendly name, based on the product
-##   name.
-## - We then ask ModemManager to ignore the serial ports on the device, and not
-##   consider them a candidate.
-## - We also tell systemd to grant access to the device (via ACLs) to the user
-##   at-seat.
-##
-## For more information about the access part, see the following resources:
-##  - https://github.com/systemd/systemd/issues/4288
