I just obtained a K800 Logitech wireless illuminated keyboard. I have a logitech mouse that works fine and also has the unifying little star on the bottom of it so it "should" work with any new unifying logitech technoligy. However, If I plug in the new USB adaptor for the keyboard, niether one works. I have also tried the keyboard with the same adaptor that the mouse uses with no luck.
I have tried plugging everything in and rebooting with no effect.
I'm on 12.04 with latest updates.
Any help would be appreciated.
NOTE: I saw others were having some issues with this in the past but, as soon as I posted a reply to the thread, it was closed.
