I purchased the Arc keyboard, USB wireless. It's sleek and makes a good looking mate formy eDge. Problem is it's not working. Batteries are in and it's a little tricky to turn on/off but I got it. My eDGe will be on, I plug the dongle in the USB port, and the screen goes off. When I take USB out it turns back on (but not a reboot). I tried turning off the eDGE and keyboard and rebooting. Nothing. Any help will be appreciated.
