I have them and have installed them.  The problem is that I am using a 
BT2.0 compliant USB dongle.  Alas, no BT2.1 compliant dongle is 
available in the US market at this time.

As above, Simple Pairing is not possible, but it does not appear to even 
attempt to fall back to legacy mode.  No messages, no errors thrown, no 
debug messages.

Agreed...my comment has to do with the fact that one MUST use 
CreatePairedDevice (at least at this point) to pair.  CreateDevice does 
not even attempt to pair (or at least that is the case if SSP is not 
available).

If you use CreatePairedDevice, you must supply an object path (valid or 
invalid) for the agent.  Therefore, as far as I am concerned, there is 
no real point to registering an agent at all, given that I must supply 
the path to CreatePairedDevice in any event.

On the other hand, if CreateDevice should trigger pairing and actually 
does, and if it can fall back to some default legacy pairing mode, well 
and good.  No agent needed at all.

I will be happy to send you mine to save you the effort, unless it 
totally sucks.

Cheers...
