[Bluez-devel] Problem with the i-Tec dongle solved

Hi Folks,

I got the problematic i-Tec dongle working. The important thing is to
send a HCI_Reset as the first command at initialization. We don't do
this, but I can't remember why not. Maybe there were some problematic
chips in the early times of BlueZ. The attached patch is against 2.6.

And here is the new dongle:

The nice thing is that it already supports AFH ;)

Regards
