The key here is that I have never seen a protocol value other than
1001, 2001, 3003 or 3004 (going from memory here, but basically I
would not expect to see "0004").

ups.power.nominal seems like it should be 1500 instead of 150. Is the
input voltage actually 120 VAC? How are the outlets grouped? (That is,
how many are switchable, and how many are on all the time?) Also, what
are the USB product and vendor IDs (available from lsusb)?

If you are mainly concerned with on-battery/on-line and low battery
indications, just hook up the unit with a dummy load (so as not to
crash the computer when the batteries die) and run the batteries down
while monitoring the "ups.debug.S" line.

Even better would be to compare values directly with what the Tripp
Lite software returns, if you have a Windows system available. If you
go that route, we could also look at a USB protocol dump.

Let me know how it goes.
