I find out one weird condition.
Once we dynamically call usb_set_interface somewhere else.
(In Alok's patch, it adjust it when hci_notify is triggered,
and the new isoc alternative setting will depend on sco_num)
The resubmit status in hci_usb_rx_complete fail with status -90.
Afterwards, no resubmit will keep working.

Is there any problem to call usb_set_interface besides of the probe phase?
