With USB-attached UPS, nut requires correct permissions not only for /dev/ugen0.* but also for /dev/usb* to perform bus scan.
I do believe that +DISPLAY for nut port should reflect this fact so one will have a chance to succeed without USB_DEBUG dance. Here is my results: battery.charge: 100 battery.voltage: 27.20 battery.voltage.high: 27.20 battery.voltage.low: 20.20 battery.voltage.nominal: 24.0 beeper.status: enabled device.type: ups driver.flag.novendor: enabled driver.name: blazer_usb driver.parameter.pollinterval: 2 driver.parameter.port: /dev/ugen0 driver.parameter.productid: 5161 driver.parameter.subdriver: cypress driver.parameter.vendorid: 0665 driver.version: 2.4.3 driver.version.internal: 0.03 input.current.nominal: 8.0 input.frequency: 50.1 input.frequency.nominal: 50 input.voltage: 230.6 input.voltage.fault: 230.6 input.voltage.nominal: 230 output.voltage: 227.3 ups.delay.shutdown: 30 ups.delay.start: 180 ups.load: 6 ups.productid: 5161 ups.status: FSD OL ups.temperature: 25.0 ups.type: offline / line interactive ups.vendorid: 0665 [eaton] driver = blazer_usb port = /dev/ugen0 vendorid = 0665 productid = 5161 subdriver = cypress novendor default.battery.voltage.high = 27.20 default.battery.voltage.low = 20.20 As you can see, I'm not using megatec_usb driver like http://www.networkupstools.org/compat/stable.html recommends for my UPS since blazer_usb has better implementation of Megatec/Q1 protocol.
