I would prefer to just disable SCO. The patch disables the main interface. Just disabling SCO means that btusb_data.isoc could no longer be treated as constant and locking for it would be necessary.

It doesn't do it that way. >From your version: if (data->isoc) usb_driver_release_interface(&btusb_driver, data->isoc); usb_set_intfdata(intf, NULL); hci_unregister_dev(hdev); First you release the interface, then you unregister the hci. > > > - it isn't carefull to kill all URBs in case of soft disconnect > > The hci_unregister_dev will be calling the close() callback.
