I've got 2.0.3 running on my XServe under 10.4.5, but I had to put a
serial adapter on the USB port instead of using a direct USB
connection. With the direct USB connection, the OS X native UPS
solution took precedence.
Anyone know how to prevent the OS X UPS handler from taking over on a
USB connection?
PS - on my 10.4 install I put the startup in rc.local as the Startup
items (even with it set to Last) didn't have enough things going to
have it work.
