That's fine when they are connecting from a computer to a printer - there'll rarely be more than a few mA on any wire and often virtually no current on +5v. No good for 500mA though. The voltage at the 'mite will easily fall by over a volt. The supply is still putting out 5v but the lead loses the rest. Better cables have fixed a few problems for the MaxiMites.
