This has worked! - I am now able to poll data from the UPS:

root# /usr/local/ups/bin/upsc mge-nova at localhost
battery.charge: 100
battery.charge.low: 30
battery.runtime: 1000
battery.type: PbAc
(etc)

Just to clarify this..  There is a bug with the USB code in FreeBSD
6.2 causing the driver to block - do you know if anyone has raised a
PR for it?

Also your comment "(so the driver only polls the UPS)" - does this
mean the UPS will not be able to notify NUT of a power failure as it
occurs, but we'll pick it up next time NUT polls?

Thanks,

Rob
