For all USA OTA digital broadcasts, select DVB as the card type.
You may first want to make sure your card is working before you do anything else. Start the system without the card plugged in. Then display a list of USB devices:
Take note of the devices is says you have. Also, output a list of driver modules currently loaded on your system:
Now open a second terminal, and enter this command:
tail -f /var/log/syslog
Now plug the USB tuner into a USB slot. Linux will detect it and display messages concerning it. Look for any messages that talk about firmware, if it is looking for any and if it finds it. Also, rerun the lsusb and lsmod commands. for lsusb, the device ID can be Googled for driver info. The lsmod output will list newly loaded drivers at the top of the list. If the /var/log/syslog output has no message concerning firmware, run this command:
dmesg | grep firmware
With this info you can find out:
1) What Linux calls your USB tuner (lsusb).
2) What drivers it uses (if they automatically load).
3) What firmware it needs to load (if any), and whether or not it finds it.
