This patch add the Dikom DK300 hybrid usb card.
The patch adds digital and analogue tv support.
Not tested: remote controller
To be done: it seems that with the proposed patch the digital
demodulator remains activated if the tuner is switched from digital to
analogue mode.
Workaorund is to unplug and replug the device when switching from
digital to analogue.
If someone can explain how to verify the gpio settings using the
usbsnoop, the above issue perhaps can be resolved.
I attach the usbsnoop obtained some month ago using windows xp.
