This looks like a pre order product. It should work using the latest firmware, if not let us know and we may be able to add support for it.
You can find the latest firmware below. Please read the instructions on the download page.
Thanks for the fast reply mist but I changed my mind, just realised that this keyboard doesn't support multiple device switching with unifying dongles..only supports 1 device with dongle and 2 with bluetooth.
I am looking for a wireless (Logitech) keyboard which supports device switching so I can have one Logitech dongle on my laptop and one connected to XIM4 and just switch between them with a key press.
My wireless mouse already have this functionality which makes device switching between XIM4 and laptop very easy, now I just need a keyboard which does the same.
