Yeah, looks all fine.

To see how all that works, you may want to have a look at:
  udevmonitor
or
  udevmonoitor --env
while you load your kernel module.

There you can watch what the kernel sends to udev and what udev is doing
with it. You can also see all the devpath's, which are the kernels key
to the device, and which udevtest expects to simulate an event run.
