Heitmueller > http://www.devinheitmueller.com > AIM: devinheitmueller Hello Daniel, Please don't top post - it's a violation of list policy. You should use the v4l-dvb repository as your base. The other repositories are temporary clones of that repository that developers used (or are using) to develop support for some new chipset. You need to put your USB ID into the driver for the ez-usb fx2 driver, so that driver will know to associate with your device. Despite the various chips being supported, you still need to tell the driver that your device contains these chips. This is done by registering your device's USB ID in the bridge driver, and then having a profile within the bridge driver that tells the kernel which other chips are used in your product. This is the same regardless of whether you're talking about a USB bridge like the Cyprus or a device that includes a PCI bridge like the cx88. Let's look at an example: The HVR-950: The HVR-950 includes an em2883 USB bridge, an xc3028 tuner, a tvp5150 analog decoder, and an lgdt3303 digital demodulator. In order to make that work, you would add an entry to em28xx-cards.c including the hvr-950's USB ID, and in the device profile you would indicate that it contains the tvp5150 and xc3028. You would also have to configure any GPIOs so that the em2883 can bring the other chips out of reset. For digital support, you would need to change em28xx-dvb.c to indicate that the HVR-950 contains an lgdt3303 and provide the required configuration parameters for how that chip is wired up in that product. For your product, you need to do basically the same thing. -- Devin J.
