Pairing a device with a Logitech unifying receiver in Linux

My girlfriend’s keyboard and mouse stopped working some time ago. It turned out that her Logitech unifying receiver (a small USB dongle for keyboard and mouse) was a bit broken, only when twisted in a certain way it would work. So, I called Logitech, explained the situation and they offered to send us a replacement for free. Well done Logitech support!

Now, since we both use Linux as our main OS, the question was how to pair the mouse and keyboard with the new receiver. Logitech provides a piece of Windows software, but nothing for Linux. It turns out it’s not that difficult and you can find various little C programmes that do it for you. I tried Travis Reeder’s solution and it worked like a charm on my Ubuntu 12.04 machine.

These are the steps I took.
First I switched off the keybord and the mouse, then ran the following:

$ git clone https://github.com/treeder/logitech_unifier.git
Cloning into 'logitech_unifier'...
remote: Counting objects: 35, done.
remote: Compressing objects: 100% (26/26), done.
remote: Total 35 (delta 11), reused 33 (delta 9)
Unpacking objects: 100% (35/35), done.
$ cd logitech_unifier/
$ ./autopair.sh 
Logitech Unified Reciever unify binary not compiled, attemping compilation
Logitech Unified Reciever unify binary was successfully compiled
Auto-discovering Logitech Unified Reciever
Logitech Unified Reciever found on /dev/hidraw0!
Turn off the device you wish to pair and then press enter
[sudo] password for lennart: 
The receiver is ready to pair a new device.
Switch your device on to pair it.

I ran the autopair.sh script twice, once for the mouse and once for the keyboard.

Thanks Travis!
