Here's the program:

  http://lists.alioth.debian.org/pipermail/nut-upsdev/2006-November/001292.html

You should be able to build it with the following command:

 $ gcc -o get_descriptor get_descriptor.c -lusb

(after installing the packages listed above)

Assuming that 'lsusb -v' (run as root) returns the same information as
Juan Pablo Valles posted on 5/30/2011, I think you'll need to run it
as follows:

 # ./get_descriptor <bus> <device> 1 0 0 128 0x22 0

<bus> and <device> are from the line of lsusb output which matches your UPS.

Juan, if you would like to try the same program, that would also be
useful to compare results.
