[Nut-upsuser] Fatal EEPROM fault!

[Sonic]

Hello,

Sorry if any of this is obvious - I'm new to NUT.

NUT via upsc is displaying (edited for length):

device.model: Eaton 5P 2200
device.type: ups
driver.name: usbhid-ups
ups.alarm: Fatal EEPROM fault!
ups.status: ALARM OL CHRG
ups.test.interval: 604800
ups.test.result: Done and passed
driver.version: 2.7.2
driver.version.data: MGE HID 1.33
driver.version.internal: 0.38

Is this possibly a firmware or configuration issue?

Does NUT report the firmware version (it's not jumping out at me in
the upsc output)?

Can NUT upgrade the firmware on this device? Eaton only seems to have
instructions for a Windows box.

Thank you,

Chris
