ug USB UPS connect. in Ubuntu

[Ruslan]

There is such a problem. UPSs are not working. Powercom and East - also.
He began to find out what was the matter. If you enter once a second, the lsusb command, then we get the following: https://ibb.co/y0nfqMQ

it turns out that he sees UPS in USB, then he does not see.
The output of sudo dmesg | grep usb is as follows: https://ibb.co/mRG548r

Here we also see the problem.
The fact is that there used to be Ub16 and there were no such problems. Installed 18 UPS powercom does not work properly on USB. You can see it on the first screen. I do every second, the USB poll command. and it is clear that the UPS then disappears for 2 seconds, then appears. The USB polling driver is unstable. At the same time, as I wrote above, this is only on some UPSs. And only starting from kernel 4.11.10 - 4.11.12. Put 16 again - no problem again.
I began to find out in more detail. It turned out that on the kernel 4.11.12 - UPS work clearly, but as soon as the kernel 4.12-rc3 was installed. Everything. problems began.
In Ubuntu 20 problem - not resolved
In Ubuntu 22 problem - not resolved

wtf??

What have you done with the kernel since version 4.12? That some UPS are now down?? Would they fix it?
