I just got my N800 a week and a half ago. I picked up a Targus USB keyboard, but I can't get it to work with the N800. I verified that it will work when attached to the USB port of my Mac. The keyboard comes with a 4-pin male to USB A male, so I had to get an A female to 5-pin male adaptor. I read one post indicating that I might need to attach the keyboard to a powered USB hub, but I had no luck with that, plugging either the keyboartd or the N800 into the hub's input and the other to an output. Ideas? Do I need to return the USB keyboard and get a Bluetooth one instead?
