Where are those rules?  Is their installation procedure documented anwhere?

Results aren't so good.  Driver still starts up on its own, but...

root at snark:/home/esr/svn/nut/trunk# upsdrvctl start myups
Network UPS Tools - UPS driver controller 2.1.0
Network UPS Tools 2.1.0 - Megatec protocol driver 1.5.3 [megatec_usb]
Carlos Rodrigues (c) 2003-2007

Serial-over-USB transport layer for Megatec protocol driver [megatec_usb]

Driver failed to start (exit status=1)
root at snark:/home/esr/svn/nut/trunk# 

That is a really uninformative error message.  How do I troubleshoot this?
