the code _is_ in src.

isoc transfer support was added to ng_ubt(4). there are some known
problems, at least in some cases system crashes when usb dongle is
simply disconnected (without shutting down the stack first). the stack
trace ends up deep in the usb guts and i had no time to look at it.

sco sockets support was also added, however 1) sco sockets hook is
*not* connected by default and 2) there are some known problems with
the code. more specifically problems are related to "broken" bluetooth
devices and the way they report sco buffer size/packet count. i happen
to have few of those devices. we need to have a way to handle those
kind of devices nicely.

before doing anything else, we need to fix existing code.

thanks,
