Ah. Never mind. It's the cx25842 (according to the chip's
ivtv-utils cx25840ctl dumps it's registers:
cx25840ctl -l [I2C Device Number]
Find the i2c chip number registered to the USB device.
# ls /sys/class/i2c-dev/ -alh
i2c-4 -> ../../devices/pci0000:00/0000:00:11.0/0000:02:08.2/usb1/1-3/i2c-4/i2c-dev/i2c-4/
Dump i2c chip #4's registers:
# cx25840ctl -l 4
