Seems there's no way to interface the chip. For some cards the MSP chip is held disabled until you toggle some gpio. See bttv-driver.c:boot_msp34xx for this : * reset/enable the MSP on some Hauppauge cards * Hauppauge: pin 5 * Voodoo: pin 20 Try pin 0-23 until the chip is "./detect"ed (or trace pcb lines). - Gunther
