I've done another test instead: connected the UPS to a windows-XP
machine, installed the manufacturer's software and tested it. It works
exactly as I would expect: after shutting down the PC, some seconds
later the OnLine/OverLoad lights on the UPS start flashing and the UPS
shuts down - or so it appears.
But now, when I reconnect the mains cable, the UPS wakes up from
standby and then wakes up the PC.

So, conclusions:
- UPS is not malfunctioning;
- UPS USB cable is OK;
- probably apcupsd on the Debian box is signalling a full shut-down to
the UPS instead of a standby command.

Anyone out there with an APC CS-500 (or similar) who recognizes the
problem and is willing to share his/her setup?
