If the interface does not exist:

Where does the kernel get the following information (have a look at the log):


"ezcap USB 2.0 DVB-T/DAB/FM dongl"..., 33ezcap USB 2.0 DVB-T/DAB/FM dongle)
I think the interface cannot be opened or the binary thinks it cannot be
opened (but it can be opened). When I plug in the stick correspondent devices
are created under /dev/usb/
