Unidentified Connected Object

I was synchronizing my PDA with Exchange, I had to stop the device and reboot it, for some reason, with the device connected it resulted in the following message.

The thing that worries me is that the driver ( I don’t have a clue here which one it is, and neither does Windows) has successfully installed. Now I wonder, how come, the driver for my Bluetooth device ( I know which one it is, and Windows knows which one it is cannot install. maybe I should have left windows in the dark about what kind of device it was.
