Sure.

Legend! I've tested https://github.com/networkupstools/nut/pull/3149 from https://github.com/networkupstools/nut/issues/3136 and can see my UPS. battery.capacity: 9.00 battery.charger.type: Constant Charge (CC) device.mfr: EATON device.model: Eaton 9PX device.serial: REMOVED device.type: ups driver.debug: 6 driver.flag.allow_killpower: 0 driver.name: usbhid-ups driver.parameter.interrupt_pipe_no_events_tolerance: -1 driver.parameter.pollfreq: 30 driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.parameter.synchronous: yes driver.state: quiet driver.version: 2.8.4.690.6-696+g7715f839b driver.version.data: MGE HID 1.57 driver.version.internal: 0.71 driver.version.usb: libusb-1.0.25 (API: 0x01000109) input.frequency.nominal: 50 input.voltage.nominal: 240 ups.beeper.status: enabled ups.mfr: EATON ups.model: Eaton 9PX ups.productid: ffff ups.serial: REMOVED ups.status: ups.test.result: Done and passed ups.vendorid: 0463

Thanks for looking into this. The service starts, but no data is retrieved from the UPS. I can see this in syslog- Fatal error: 'synchronous' is not a valid flag for this driver. Followed by many lines of - Poll UPS [[email protected]] failed - Driver not connected I also tried synchronous = yes but received the same as before: 2 different HID descriptors Unable to get Report descriptor: Resource temporarily unavailable nut-debug-20251021055120.zip

Hello, Just purchased an Eaton 9PX and the driver doesn't seem to load when connected via USB. I've tried different USB ports, cables, motherboards (2nd Unraid server), 2.82 through to preview builds of NUT. Attached debug file. I wanted to check if there's anything I can or should do to get this working before I get a network card for this unit. nut-debug-20251019122507.zip
