For what it's worth;

After having cross-compiled to my embedded system and leaving the USB-dongle solution behind, everything now works like a breeze and I now have a BT device hosting running 2 SCO connections and 3 RF_COMM sockets simultaneously.

Thanks for your help along the way!

Ok -- that does make my life a bit easier ;)

The target-platform for my app is indeed an embedded one with a serial interface to a BT module, so that's fine... However I'm developing the app on a "real" computer using an USB dongle, but I'll try to cross-compile and go for the intended target-platform instead and keep my fingers crossed...

Thanks all for your input!

My spontaneous reaction would be; really?


My code is based on the socket-abstraction in BlueZ and it works fine
for multiple ACL connections
    
Marcel says the usb layer needs a rewrite to accommodate this. It has
something to do with resource allocation on usb iirc.

It does work now on systems that use a serial hci connection (mostly
embedded) but that may not help you.

now?
