Use the "PROGRAM=" key in a udev rule.   If the rule is only ever executed for 
your prism2 device, then it can safely always return exit code 0.  Strictly, 
this is intended to run a program which will determine if this rule is to be 
applied to a particular device, but nothing says it can't have side effects.
