I've read that any usb keyboard should be able to work on the tablet but when I plug in the keyboard to the usb slot the only thing that works are two of the function keys to control the volume (and they are actually reversed - volume + key actually turns the volume down on the tablet and vice versa). I have a microsoft usb keyboard that works great on my pc and figured I'd see if it does the trick on the tablet. Perhaps there are drivers that I need to install, how do you do that on a tablet (windows 7 is plug and play ready so I never worried about it on the pc)? There's obviously communication going on as the function keys work to turn the volume up/down using the usb keyboard but the rest of the keys aren't responding. Any help out there?
