Anders,

> Does ng_ubt support Bluetooth 1.2 devices? Are USB dongles with Bluetooth 1.2

> DBT-122 (1.2) device.

in general, yes, bluetooth v1.2 devices will work with ng_ubt(4) and 
bluetooth stack. i have v1.2 device and it works just fine. keep in mind 
that ng_hci.h does not yet have definitions for bluetooth v1.2 hci 
commands and events. it does not mean that you can not send these 
commands to the device.

thanks,
max
