Title:
  bug USB in Ubuntu

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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:

[url=https://ibb.co/y0nfqMQ][img]https://i.ibb.co/y0nfqMQ/zevstst-u18-lsusb.png[/img][/url]

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

[url=https://ibb.co/mRG548r][img]https://i.ibb.co/mRG548r/zevstst-u18-dmesg.png[/img][/url]

  Here we also see the problem.
  The fact is that there used to be Ub16 and there were no such problems. 
Installed 18 - and started. 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.

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