Hi Charles,

The Windows software also reports protocol 0004.  This is an old unit,
probably 5 years old or so.  I looked, but didn't see any way to update
firmware on this UPS.

It's a 1500VA, so yeah, no idea why it reads 150.  Input is 120V.

There are two load groups, load 1 is switchable, and has two outlets on
it.  load group 2 is not switchable, and contains the other six outlets.

I'm running Nut in an embedded environment, and don't have lsusb
available.  I can setup Nut on my laptop for testing if need be, but
here's the relevant section of /proc/bus/usb/devices:

My primary concern is battery status, but it would be nice to have all
the other features too.  I can hijack my wife's laptop for awhile to do
the dump, but I'm unfamiliar with the internals of the PowerAlert
software.  What do I need to do to get you the data you need?
