The problem is not to connect to 7 devices simultaniuous. The problem is
that (on the HCI level) most (or all??) devices gives you an error
response when you start a new connection while there is an outstanding
connection request. Of cause you can come arround this by software on the
upper level. E.g. you can make sure not to send a new connect request to
the device while it has not responeded to the previous one.

Don't know what microsoft is doing here (don't have their source ;-).

Ciao,

Peter
