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_64
nut-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 UPS
However, 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@fedora <mailto:root@fedora> ~]# nut-scanner -U
Scanning 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@fedora <mailto:root@fedora> ~]# /usr/sbin/usbhid-ups -DDDD -a eaton5e

(If I run it with -u root it tries to read my headphones and other USB devices,
but the UPS still has the same result.)
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
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.
