Wiring diagram with USB/peripheral CONNECTIONS

[damunk]

Let's say in the conventional single phase electrical schematic drawings there is a pc motherboard. All the voltage lines, MCB's etc have been done. How would you now show for instance ; USB from the PC motherboard to a peripheral device such as a printer.

Would it be a straight solid line same as the voltage/earth lines or would it be a dotted line?
