Comment 0 for bug 1072082

I recently purchased a new Logitech K350 keyboard (UK layout) and M505 mouse, both of which use the Logitech Unifying Receiver. I 'paired' the keyboard and mouse to the receiver by using the proprietary Logitech 'Setpoint' software on a friend's computer running Windows XP. On their computer, the receiver, keyboard and mouse worked perfectly.

I then moved the receiver to my own computer, a new Dell Inspiron 7520 SE running under Ubuntu 12.04.1. I tried with no success to get the keyboard and mouse to work by repeatedly unplugging and re-plugging the receiver, and by re-booting the machine.

I experimented with solutions posted on the web, in particular in this thread on Ask Ubuntu (http://askubuntu.com/questions/128345/logitech-m515-does-not-work-after-upgrade-to-12-04/202627#202627). The accepted answer did not solve my problem, but I found a workaround posted by one of the other respondents, referring to a script published in this Launchpad bug report (Bug #1039143)(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1039143).

Running the workaround script on the command line enabled the receiver. I added the script to crontab as suggested. The script does not cause the receiver to work after a reboot, but I found that a single unplug/replug cycle was now sufficient to restore operation of the keyboard and mouse.
