A program to pair devices to a Logitech Unifying Receiver on Linux.
Logitech only provides a Windows program to do this, so if you're running Linux, you either need to pair your devices on a windows box or use the unify.c script.
1. Compile it
gcc -o unify unify.c
2. Find your hidraw device
To find it, run the following for every hidrawX on your system until you find HID_NAME=Logitech USB Receiver:
cat /sys/class/hidraw/hidraw0/device/uevent
If hidraw0 isn't it, try hidraw1 and so on.
3. Pair it
Run:
sudo ./unify /dev/hidrawX
Where X is the matching number from step 2.
4. Turn on your device like the tool will say.
That's it! Device should work now.
