Hello,

I have issues using "voice"/HSP/HFP profiles with this headset and
latest kernels/bluez cvs.

It seems it tries to use extended SCO when it shouldn't...

hcitool info xx:xx:xx:xx:xx:xx
Requesting information ...
	BD Address:  xx:xx:xx:xx:xx:xx
	Device Name: Motorola HT820
	LMP Version: 2.0 (0x3) LMP Subversion: 0xa41

	Features: 0xff 0xff 0x8b 0x78 0x18 0x18 0x00 0x80

		<park state> <RSSI> <channel quality> <SCO link> <HV2 packets> 
		<HV3 packets> <u-law log> <A-law log> <CVSD> <paging scheme> 
		<transparent SCO> <broadcast encrypt> <enhanced iscan> 
		<interlaced iscan> <interlaced pscan> <inquiry with RSSI> 
		<AFH cap. slave> <AFH class. slave> <AFH cap. master> 
		<AFH class. master> <extended features> 

An other headset which support eSCO, works fine :

		<EV4 packets> <EV5 packets> <AFH cap. slave> <AFH cap. master> 
		<EDR eSCO 2 Mbps> <3-slot EDR eSCO> <extended features> 

What can I do to help now ?

Best regards,
