I want to add that I managed to find a kernel list post
	https://lkml.org/lkml/2018/11/26/580
	[PATCH 4.19 038/118] Revert "HID: add NOGET quirk for Eaton Ellipse MAX UPS"

Suggesting that in Nov/18 a quirk for EATON was removed in kernel 4.19, which seems
to match the finding that the failures started between 4.18.16  and 5.0.9.

Looking further into the issue I understood that I can set a quirk using module parameters.
usbhid is built in (not loadable) so I set a kernel boot parameter
	usbhid.quirks=0x0463:0xffff:0x08
and now it seems that the ups comes up OK.

I will keep an eye on it.

cheers
