The real problem is that (all ?) Bluetooth hardware devices do not allow a second connect request while another connect request is pending.

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.

As far as I know the Microsoft Stack only supports USB devices, so you need some sort of USB Monitor (e.g. snoopy) to trace the HCI traffic. Have not tried it, but snoopy is GPL and it may be possible to hack it in a way that it gives you something usefull.

I tested this on my old HP nc4000 and with a Bluetooth 1.1 chip in it and it works fine. Maybe your dongle send back the wrong command or is doing something else wrong. With a CSR dongle however this seems to work without any problems. Check what "hciconfig -a" tells you about your dongle.
