if I would know of any other manufacturer information, I would have put
them on my webpage.

This is not controllable from the HCI. You can only check the current
value if it is supported and if the command is really implemented and
not only a fake one.

Get yourself a CSR based one or upgrade a D-Link DBT-120 Rev. B3.
As long as you don't care about the inquiry with RSSI, then you might
also be happy with a Broadcom one or a Silicon Wave. However the
Broadcom doesn't support this it all and the Silicon Wave are buggy.
Actually I am waiting for the first CSR based Bluetooth 2.0 + EDR
dongles to appear on the market.

Marcel
