UPS usb connection issue

Jaksparro98 · December 18, 2020, 1:54pm

Hi all, I’m facing a weird problem regarding the connection between a UPS and the FreePBX system, now the introduction:

I have a Legrand Keor SP 800 that I’m trying to install, the manufacturer have the linux daemon for reading the data coming from the UPS via usb, the only problem is that the device isn’t sending anything, when hexdumping the device on hidraw* I catch nothing, but when I try to connect the UPS on another linux machine it sends events properly, I’ve done a fresh install and migrated from 14 to 15, I even tried to install a virtual machine with the same version of FreePBX and loaded the 14’s backup, the usb does “talk” with all but the machine in production.

I’m out of ideas, it’s over one month now, my last suspects are there is something in the HID descriptor of the device it doesn’t like or the usb controller on the server is somewhat messed up.

Preventively I leave some info about the device:

So hardware seems to working, Next make sure there is traffic

When plugging the usb there is some initial traffic but nothing else

this is what i get by reading the usb from the system where it works (about 20 seconds of capture)

I would go to the author of the ‘server’ for the device,

cynjut · December 18, 2020, 4:57pm

The Legrand seems to be supported in the Sysadmin Pro UPS setup. If you are using the distro, it might be worth your time to check that out.

Also, the Legrand appears to use the USBHAL extension which may or may not be correctly installed with the system.

Jaksparro98 · December 18, 2020, 5:14pm

do you see something off? sorry but I don’t have a good eye in spotting issues based only on these captures, when you say “the author of the ‘server’ for the device” do you refer who gave us the machine? I only know it was the leftover of a desktop pc.

Jaksparro98 · December 18, 2020, 5:21pm

We do not have Sysadmin Pro and I’m afraid that I will need to solve the problem without it, we have already faced issues that could be easily solved by having the module installed but every time I had to find a workaround.

Apart from that, what really puzzles me is the motivation behind the device refusing to even send data through the raw channel, hidraw0 in this case.

Tell me more about that, can’t find more around, also I would exclude it since the same identical system is on a virtual machine on different hardware (working as expected), unless it is something is installed when FreePBX itself is installing

Jaksparro98 · December 23, 2020, 10:49am

@dicko

Any other idea?
your last answer was a bit cryptic, I can only assume there is something wrong with the server machine, I can provide some other info if you feel like it.

dicko · December 23, 2020, 1:19pm

Your problem is unrelated to FreePBX , the manufacturer of your hardware apparently provide a ‘device driver’ which they apparently call a ‘server’ , this needs to be kernel specific, you need to find out if they have a compatible driver for your kernel.

Jaksparro98 · December 23, 2020, 5:30pm

I will try to contact the UPS manufacturer then, thanks for the time.
