Hello again, This an other patch that allows my dongle to be configured correctly for the voice/sco profile. I already sent one for hci_usb some time ago, so it may sound familiar, but it probably didn't have correct style... Regards, Guillaume B. PS: The HT-820 combo headset can now quite reliably use alternatively voice and hi-fi profiles (and the keys). This sometimes makes pulseaudio crash though. Anyway, thanks for your hard work.
