Davide, given that your device has a VID:PID pair of 0xffff:0x0000 I assume you're using the 'krauler' USB subdriver. If that's the case (and it should be, at least going by the upsc output you posted some time ago), then be aware that the driver -currently- doesn't support shutdown commands: http://www.networkupstools.org/docs/man/nutdrv_qx.html#_implementation_notes Starting from 2.7.3 (some bugs have been fixed after that release and, hence, I'd recommend current git HEAD) nutdrv_qx has a new USB subdriver ('fabula') that's somewhat similar to the 'krauler' one and that supports shutdown commands (but it still ignores ups.delay.start/ondelay and makes the UPS turn on the load as soon as power is back, as per my previous link): it may (or maybe not) work with your device. Once installed the new version, you should be able to test the new subdriver specifying in ups.conf something like this: [ups] driver = nutdrv_qx port = auto subdriver = fabula vendorid = ffff productid = 0000 If you still don't have luck with the new subdriver, then -provided that you have enough time (and patience to put up with me)- we can try to see if we can add support for shutdown commands to the 'krauler' subdriver.
