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

[Louis van Dyk]

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"	product = "5E"	
bus = "002"I have put that exact info into /etc/ups/ups.conf - it's the
only info not commented with a # in the file.  I changed the name to
eaton5e though.
When I then run:  [root at fedora ~]# /usr/sbin/usbhid-ups -DDDD -a

(If I run it with -u root it tries to read my headphones and other USB

So my problem is:   2.024099	Trying to match device   2.024122	
Device matches   2.024134	failed to claim USB device: Device or
resource busy   4.898305	detached kernel driver from USB
device...   4.898344	nut_usb_set_altinterface: skipped
usb_set_altinterface(udev, 0)
Please could you assist me in getting the driver to load and
successfully connect?
Many thanks,Louis
