Unfortunately, where-ever you read it, is wrong. Digital Photography is just that, digital. It is just bits of data. These travel along the circuits and wires of your camera, computer etc. This data either gets transmitted and received, or it doesn't. There is no way that certain selective segments of information are not transferred just cause you plug into the system a different way. If a failure takes place, it isn't selective about which bits of data it succeeds in transferring. It is all just zero's and one's when it comes down to it. The cabling has nothing to do with the speed of the transfer either, it just transports what is given to it, at the speed it is given it. The connections at each end are the important bits when it comes to speed.
