[Nut-upsuser] Eaton 5E 1100i USB UPS - failed to claim USB device error

Wed Aug 19 12:54:28 BST 2020

Hi,

An alternate suggestion instead of modifying grub config. You can try
the following

create a file "/etc/modprobe.d/ups-usbhid.conf"
append / add the line below
--8<--
options usbhid quirks=0x0463:0xffff:0x08
-->8--

I hope that is true and that I haven't been wasting effort on a faulty device.  I have tried with my printer's USB cable and seen the same thing.  I then tried it on my laptop (also on Fedora 32) with the same result.  To me this eliminates my PC and the cabling.
