Had this ups, turns out the special treatment for this UPS was removed at some point
when it was thought that it is not needed anymore...

I manually enabled the quirk with a kernel boot option
	usbhid.quirks=0x0463:0xffff:0x08
Append this to GRUB_CMDLINE_LINUX_DEFAULT in /boot/grub2/grub.cfg

I do not have a record of the source of this advice, I found it searching the 'net.
