Hi Martin,

have you shared the device, in VBox ?
Ie, allowed explicitly your VM to use the UPS, or even exclusively?

try grouping your efforts, FreeBSD knowledges (I'm a newby there) and

you may also try with Linux first, to get around a possible device issue
with the driver, and then get back to FBSD...
