Look to /etc/udev/rules.d
HTH
I think I should be able to define an appropriate rule for my unit, but
I'm surprised to find that the udev doc does not mention a key
containing the device type or vendor/product id (as reported e.g. in
/proc/scsi/scsi.) Is there really now way to do direct match on those?
