I guess the compatibility page is no longer generated from this list. The
fact that 'compat.html' no longer exists, but is now split into
'compat/dev.html' and 'compat/stable.html' is indicative that something
has changed too.

I agree with you that we should update this file more frequently and
preferably should be generated from the 'driver.list' file. However, I
don't know if this is still possible, since the hosting of the site has
changed a while ago.

For a UPS with a USB connection, there is a fair chance that it is
supported via the 'newhidups' driver and autodetected. Other than that,
the answer is 'no' (unfortunately). The serial PnP signatures for UPSes
with a RS-232 interface are not collected presently and many don't even
support serial PnP at all (with a few exceptions, almost all contact
closure type ones).

Autodetection should not be a function of NUT, but rather be build into
the OS, since many more devices may be detected that have no relation to
NUT. Having each project write its own autodetection mechanism is wasteful
then or confusing at best. We have just started investigating if we can
integrate NUT this via HAL, but it is way too soon to see if and when this
will be possible. In the mean time, a configuration wizard that scans for
devices that *do* support serial PnP might be helpful.

In that case it might be better to just post to users, since most
developers will read that too.
