  Two questions: first of all, in a situation like mine (HID UPS) and 
assuming the UPS is actually supported, what are you supposed to have in 
the "port" entry in the ups.conf file? I tried the obvious at first 
(ttyS*), then tried /proc/bus/usb/001 (taken from my system) a minute 
ago after reading your reply. No joy. "No matching USB/HID UPS found" 
message after I "upsdrvctl start".

  Second: this UPS comes with the UPSilon2000 software from Megatec, and 
Megatec protocol is supported by NUT (or is it the RS-232 version being 
supported?), right?

Thank you for your reply and explanations. I really want and need to get 
this thing to work. I'm a total newbie to USB and NUT, so be patient if 
I ask silly questions ;-) .
