Hmm that seems odd. It should be even my USB devices show up in Device Manager. Do you have the little icon in you task bar that says to safely remove hardware? If so check in there maybe it has the info you are looking for.
i have got the little blue icon in my task bar, and when i click on that it gives me the bluesoleil application.
aha in the blue soleil application
i found the device address 00:11:...
and the following hardware
Manufacturer: Integrated System Solution Corp.
HCI Version 1.2
HCI revision 1F4
LMP Version 1.2
LMP Sub Version 1F4
googled for HCI, LMP and found out the following
HCI Host Controller Interface
LMP LInk Manager Protocol
still have not been able to work out what is the versio nof bluetooth
i guess the services possible with a bluetooth device are determined on the application level, and since i have got the bluetooth device plugged into my pc hence there are a whole bunch of services available to my bluetooth dongle.
