the dumps are fine. With inquiry mode 0 you see only Inquiry Result
events and with inquiry mode 1 (in your case the default that hcid will
set on adapter init) you see only Inquiry Result with RSSI events. The
Linux kernel and hcid+hcitool are capable of handling all for possible
events that are out there:

	inqmode 0: Inquiry Result
	inqmode 1: Inquiry Result with RSSI
	inqmode 1: Inquiry Result with RSSI and Page Scan
	inqmode 2: Extended Inquiry Result

The Inquiry Result with RSSI and Page Scan shows only up on a couple of
broken Silicon Wave based adapters where these guys where to stupid to
read the final Bluetooth 1.2 specification. However BlueZ works around
their mistake.

It seems that kdebluetoothd needs to updated and the best would be if
they start using the new D-Bus interface, because this takes care of all
this adapter specific things.

Marcel
