Allright, the new version of iwmbtfw from git supports 72XX BT
interfaces and the firmware directory needs to be specified:

iwmbtfw -D -d ugen0.3 -f /usr/local/share/iwmbt-firmware/


Also the /etc/devd/iwmbtfw.conf needs a tiny update so it also flashes
firmware to PID=0x0a2a automaticaly with devd:

match "product" "(0x0a2a|0x0a2b|0x0aaa|0x0025|0x0026|0x0029)";


Thank you for this stuff ! :-)
