I have an old HP BT foldout keyboard that i used with my iPaq. It has the SPP or SSP profile on it so i know its not an HID device. I did hours of searching on google and other forums like this one trying to find someone who has drivers or instructions on how to get these two talking. maybe im searching with the wrong words but i cant find anything. i know freedom input has a very similar keyboard but i guess they want to sell me the drivers. now, call me cheap but i already spent $125 on this keyboard, i dont want to have to buy drivers too!
