We currently have no driver that knows these IDs.

This is bad. Forget about the 'newhidups' (or the 'usbhid-ups' driver it
is called now). This is not a HID Power Device, so that driver will not
work.

There are a couple of drivers you could try:

1) megatec_usb requires adding '-x vendorid=0590 -x productid=0058' and
either '-x subdriver=krauler' or '-x subdriver=agiler'. This is probably
the quickest to try out.

2) bcmxcp_usb doesn't honor '-x vendorid' yet, so you need to modify the
nut_usb.c source file to try this one out.

3) tripplite_usb requires a change to the driver, since the vendorid is
hardcoded. It does honor the '-x productid=0058' though, but that alone
will not make the driver work.

The above is basically all we have to offer now. Most of these devices use
non-standard protocols, so it is most of the time trial-and-error to get
these devices to work.

Make sure that you are *not* powering anything when doing your
experiments. The UPS may misinterpret commands or even suffer permanent
(firmware) damage when trying out different drivers, so you have been
warned.
