I don't think so, because this is some kind of init problem. You can try
to set the quirk for your device 0a5c:2009 to HCI_BROKEN_ISOC only,
because it seems that parts of it still work if you don't call reset.
Btw do you compiled your kernel with the CONFIG_BT_HCIUSB_SCO option? If
yes, then try without it.

The other thing is to change the init sequence of HCI commands and
actually for this I must have this dongle at home. Think about donating
it to me instead of returning it.

Regards

Marcel
