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.
Regards
Malcolm
