Please post the first 30 seconds worth of

     /path/to/usbhid-ups -DD -u root -a upsname > APC_CS500.txt 2>&1

here. Make sure to stop any running driver before doing so and be so  
kind to zip the resulting logfile.

This version is way too old to be of any use. We already know that  
0xff86007c is APCDelayBeforeReboot and we already try that after the  
shutdown.return command fails. Only if that one fails too, we use  
load.off.delay.

This is what the nut-2.6.0 usbhid-ups driver will do by default, so  
I'm not surprised. Double check which version of the driver you're  
running in your tests (preferably by checking with 'upsc'). I will not  
answer further messages unless you make clear which version of the  
driver you're running and whether or not you modified it.

Best regards, Arjen
