well, the packages (and ipk are iirc kinda simplified debs) are quite
the "nut" package (for example on Ubuntu) includes the core and the
serial/usb drivers, with the udev file and so on. the hal support is in
another packages that is conflicting with the "nut" one (in order to avoid
runtime conflict between the classic and hal drivers).

The error:

yup, 2nded.
Greg: can you try again this test please.

I've just made some test on PW5115 500i (500VA), nut 2.4.1(-2 ; packaged) on
an Ubuntu 8.10. Everything was fine. same goes for 2.2.2 (from source this
the firmwares are:
- USB: 01.00
- Main:10.04

This is the only 5115 I have underhand, but what is puzzling me is the exact
model name:
- mine (with 2.2.2) displays "Model = PW5115 500i         500VA"
- while Greg's displays        "Model = 51150500A           500VA"

a subtle difference! though the 2 firmwares (USB and main) are identical.
iirc, this value (the name) can be changed. Have you done so Greg?

I'm still learning PW, and will have to check with the PW people there.
more info soon
