FWIW, the RS-232 spec explicitly states that the interface electronics
will be immune to any short-circuit or misconnection of the pins. I
have no idea if USB and FireWire have such a provision, but it *would*
be nice.

Can you advise what RS-232 is? What relation does this have to Firewire?

The standard serial interface, used for modems, printers, mice, and all
sorts of other things before USB came along. Has some advantages over
USB, like it works fine from one end of a building to the other and you
can easily make your own cables, but isn't designed to support hubs with
multiple attachments and is relatively slow, especially compared to USB2
Hi-speed.
