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. HH "racer" wrote in message ups.com... hi the usb suplies power when the main power is off what current (ma) does it supply? |

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