First of all, it is a terribly bad idea to run a driver in debug mode  
on a production system. It should be used for testing purposes only.

The problem is caused by the driver failing to detect a working  
'load.on.delay' command for the UPS, which is needed to create the  
two-step 'shutdown.return' command. Either your UPS doesn't have one,  
or it is put in a vendor specific HID path. Because of this, the  
driver will fallback to the 'shutdown.reboot' command, which seems to  
be horribly broken for your UPS.

It would be helpful if you could post the output of

  /sbin/usbhid-ups -DD -a scups 2>&1

here, so that we can see if there might be another HID path that could  
be used.

Chances are, that we just need to call 'load.off.delay' and that the  
device will return power all by itself. This violates the HID Power  
Device Specification, but since the 'shutdown.reboot' also is  
non-compliant, I'm not too surprised.

Best regards, Arjen
