It certainly should NOT be supplying power with the system shut down.
Something is very wrong there. Dunno about milliamperes but it is 5V, IIRC.

Whoa there...some desktop systems *do* in fact keep their USB ports powered
when the power is "off". This is probably perfectly normal and nothing to be
worried about.

The official spec for USB is 500mA at 5 volts DC. Most ports will stand
more. If your computer keeps the ports energized when turned "off", you may
not want to put a heavy load on them, as they may be getting power from the
+5 volt standby supply.
