Created by: KingYes

Hi ! I install your Solaar on my system(3.9.9-1-ARCH), and I can't get it work..

In my first time when I running your scripts, It's really detect my Touchpad. But I press Unpair, and after this I try to pair it again and again, but no result.

BTW, when I run with cli tool, this is what I get:

 $ solaar-cli pair
Traceback (most recent call last):
  File "./solaar-cli", line 42, in <module>
    solaar.cli.main()

    args.cmd(receiver, args)

    known_devices = [dev.number for dev in receiver]

    known_devices = [dev.number for dev in receiver]

    dev = self.__getitem__(number)
  File "/home/yakir/Aur/Solaar/lib/logitech_receiver/receiver.py", line 461, in __getitem__
    return self.register_new_device(key)
  File "/home/yakir/Aur/Solaar/lib/logitech_receiver/receiver.py", line 405, in register_new_device
    dev = PairedDevice(self, number, notification)
  File "/home/yakir/Aur/Solaar/lib/logitech_receiver/receiver.py", line 119, in __init__
    self._codename = codename[2:].rstrip(b'\x00').decode('utf-8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa7 in position 4: invalid start byte

Thank you for support !
