fyi... over a year ago, Marcel wrote this cryptic note on multiple sco
connections:
===========
starting with 2.6.10 the hci_usb got a module parameter "isoc". This
controls the alternate setting when plugging in a dongle. The default
value is 2 (or 0 if it is blacklisted device). Check the Bluetooth
specification what value you have to choose for 2 x 16-bit SCO channels.
===========
If you're not able to find that value, you could try experimenting with
different values.
I was not able to find out what happens if the value is set higher than
you really need it. Would it hurt to load hci_usb with isoc set to the
value for two headsets even if you usually only use one? I don't know.
