Allow SCO with Asus WL-BTD202 dongle in btusb

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.

This patch allows the 0b05:1715 Asus WL-BTD202 dongle to be used with a SCO headset with having to specify "options btusb force_scofix=1".

Hi Guillaume,

you have to prove this one. Boot a kernel without the patch and call hciconfig hci0 up and then show me the output of hciconfig -a.

Marcel

The file "hciconfig-...-before" was the output without the patch. The file "hciconfig-...-after" is the output with the patch. The last file contains some info from "/proc/bus/usb/devices".

Is it just proof that my dongle's firmware is out-of-date ?

Regards,

Guillaume B.

Hi Guillaume,

I applied a modified patch to my tree since it didn't apply clean anymore. Thanks.
