I think that this is basically the NogaTech reference design (based on
the information in "USB by Example" by John Hyde) - at least the video
part anyway.
Can you guys confirm that the NT1003 is providing the I2C bus mastering,
and that the SAA7111A (video codec) and FM1216 (analog front end?) are
I2C bus slaves. Is the 4052 an audio codec? Is it also I2C controlled?
Do you also need HID out to set up the NT1003 and other devices?
