Public bug reported: Binary package hint: dvb-apps
I have an Aopen MP45-DR mini-pc. I am trying to get a DVB card working in it. The DVB card is a Mini-PCI express card. It fits on a minicard slot inside the pc. I can activate the 'Firmware for DVB cards' in the Hardware Drivers applet: Oct 24 10:59:14 wulf kernel: [ 121.660518] usbcore: deregistering interface driver dvb_usb_dib0700 Oct 24 10:59:14 wulf kernel: [ 121.692684] xc2028 6-0061: destroying instance Oct 24 10:59:14 wulf kernel: [ 121.692899] dvb-usb: YUAN High-Tech STK7700PH successfully deinitialized and disconnected.
