it might be possible, but L2CAP is SOCK_SEQPACKET and RFCOMM is
SOCK_STREAM. You should keep this in mind and also is written in the
profile specifications.

Take a look at l2test and rctest from bluez-utils.

It uses it for SCO support.

Disable SCO support for the USB driver and no ISOC transfers are used.
