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

Hi
BACKGROUND INFO:I have a new Eaton 5E 1100i USB UPS which their website
claims is supported on Linux.  They don't provide software for it for
Linux, only for Windows.Referring links:
https://www.eaton.com/za/en-gb/catalog/backup-power-ups-surge-it-power-distribution/Eaton_5E_UPS.html
https://www.eaton.com/za/en-gb/skuPage.5E1100IUSB.specifications.html
It was manufactured in May 2020 according to the sticker on the box.
I am running on Fedora 32 with all the latest patches.  I installed nut
and nut-client from the Fedora repository, which provides version nut-
2.7.4-27.fc32.x86_64nut-client-2.7.4-27.fc32.x86_64
On https://networkupstools.org/stable-hcl.html I am told that it is 5*
green "vendor provided protocol and hardware" using usbhis-ups as a
driver.
PROBLEM:1.  The UPS is listed in "lsusb" as Bus 002 Device 101: ID
0463:ffff MGE UPS Systems UPSHowever, I notice that is disappears and
reconnects every 19 seconds.  I've seen some posts noticing this too,
and stating that it stops once it is successfully connected to the
software.  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.
2.  The device is detected by "nut-scanner -U" as:root at fedora ~]#
nut-
scanner -UScanning USB bus.[nutdev1]	driver = "usbhid-ups"	port
"auto"	vendorid = "0463"	productid = "FFFF"

it's the

Please could you assist me in getting the driver to load and
successfully connect?

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.

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

Thank you Eyal!!

Adding 
usbhid.quirks=0x0463:0xffff:0x08
to the kernel boot parameters did the trick for me.

FYI to those using Fedora 32, to edit the command line use the tool
"grubby" as follows:

grubby --update-kernel=ALL --args="usbhid.quirks=0x0463:0xffff:0x08"


@DEVS:  Could you please re-add the code for using this UPS?  It's
still being sold fast and furious in our region, and I'm sure more
people are having the same problem.

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've seen some posts noticing this too, and stating that it stops once it is
successfully connected to the software.  I hope that is true and that I
haven't been wasting effort on a faulty device.  I have tried with my

 I've seen some posts noticing this too, and stating that it stops once it
is successfully connected to the software.  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.

The correct file to edit is, of course, /etc/default/grub, and not
/boot/grub2/grub.cfg
where there is no GRUB_CMDLINE_LINUX_DEFAULT.

However, the other suggestion of adding a file in /etc/modprobe.d/ is the better
way
to add a module parameter without bothering with grub.
