OK, your UPS doesn't have 'ups.timer.start'. That's not required to  
shut it down, but this means that there will be no way to shutdown  
with a delay and return when the power comes back. The fallback  
'shutdown.reboot' command immediately shuts down and returns after a

This is an internal (driver) command, so this is what we expect here.

If you don't have 'ups.timer.start', 'load.on.delay' (which is the  
command that sets this timer), won't work either so this is no surprise.

But this is a problem. Since the requirements for 'shutdown.return'  
are not met, the driver should (and indeed, does) fallback to  
'shutdown.reboot'. However, this command is not accepted by the UPS,  
although it is advertised in the HID report descriptor. This is ugly.

I'll see what I can do for you to work around this problem. Can you  
build your own packages from SVN? This would be helpful in getting  
this fixed quickly.
