Yes you must have i2cdetect intstalled from the lm_sensors or i2c-tools
package. You must also have the i2c-dev module built. Modprobe the
i2c-dev module, have i2cdetect list the busses, then run i2cdetect to
check for the Z8 chip on each ivtv i2c bus.
# modprobe i2c-dev
# i2cdetect -l
i2c-0 smbus SMBus PIIX4 adapter at 0b00 SMBus adapter
i2c-1 i2c ivtv i2c driver #0 I2C adapter
i2c-2 i2c cx18 i2c driver #0-0 I2C adapter
i2c-3 i2c cx18 i2c driver #0-1 I2C adapter
# i2cdetect 2 0x70 0x71
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-2.
I will probe address range 0x70-0x71.
