I could well be wrong John but I imagine the USB thingy a bit differently. The way I picture it, it could be broken down into 3 components:

IDE (or SATA) interface for the hard disk(s in some cases?)
IDE to USB (bulk storage device?) converter.
USB interface for the computer.

By this reasoning, while there may be various names that might even amount to the same settings, ie. default, master, stand alone, that may work, I'd not expect the drive to work as a slave. I've no idea whether any would work in a cable select mode.
