Hi antti There some issues with dvb_usb_v2 with the lmedm04 driver. The first being this patch, no return value from dvb_usb_download_firmware causes system wide dead lock with COLD disconnect as system attempts to continue to warm state. The second is to do with d->props.bInterfaceNumber in patch 2. In get_usb_stream_config there no handing of the struct dvb_frontend. ... int (*get_usb_stream_config) (struct dvb_frontend *, struct usb_data_stream_properties *); ... I wonder if it would be better to use adapter instead? I also have a draft patch to use delayed work.
