I have wireless keyboard Logitech cordless desktop EX110. Mouse sometimes stops working (sometimes after a few hours working and sometimes after 10 minutes working). I get it back to life by unplugging it from the computer case and then plug it.

Is there a way to do it via console? Maybe by restarting the usb port.

This is the lsusb listing.
