  Ok, it was bad error message from driver. Really, problem was in
access rights to /dev/ugen1.2 node :)

  Now I have another question: devfs(8) uses device types or paths to
specify access rules for /dev/*, which is bad idea for USB device, as
it will change path when cable will be re-attached to another port. Is
here any method to set owner:group of device node by VID/PID or ID
string or something like this?
