The only "bad cables" I've heard reasonable explanations for are the round cables that Joe Ross reported do not have all of the pins connected. As for the other reports, I have no idea how much of that is speculation or other variables that are not being accurately conveyed here. The I2C signals only operate around 150kHz on the digital side car, so I don't expect any there is any cable quality problem that would cause issues, short of "the pins aren't connected at all". I suspect there are other problems like poor soldering, very long cables between the DSC and the sensor, damaged sensors due to hooking up power and ground backward and some point in the past, etc.
