apart from the good advice from George (Ross), we need the following
info to be able to help you (both need root privileges):

- the nut version used,
- the operating system, and version, you're running,
- drivers debug output:
$ /path/to/driver -DDDDD -a <devname>

- and for the USB side:
$ lsusb -v -d051d:<productID>

AFAICT, the serial protocol has changed (and is not published nor
reverse engineered), but USB should work (minus a possible missing
supported productID).
