Driverless Bluetooth?

I'm looking for a driverless bluetooth adaptor I could use to connect an Apple Bluetooth keyboard to a Windows XP-embedded computer that recognizes standard USB keyboards but I don't have access to install bluetooth drivers. So I need a device that either needs no setup with the keyboard (truly plug and play) or I can setup on another machine and the profile is stored on the dongle so I can plug it into the embedded machine's USB port and it will recognize the keyboard as if it were hardwired.



Do you have any recommendations? Your help is GREATLY appreciated!
