    The cable from the computer to the hub should be no more than maximum 5 meters. That's the maximum signal length specefied in the USB 2.0 documentation.

    Have something to to about low current and signal noise.

    500mA is the maximum per port on a USB 2.0 externally powered hub. The PC ports can supply 1A or more. That's why it works that way. Just tap into that supply and power the drive if it has a barral connector or a USB Y if not. It will work fine.

    gotcha, ill throw that around, due to the lack of space in my dash i had to solder the usb cable directly to the circuit board inside the external drive, so either ill add a power cable, or maybe ill solder a Y USB cable instead.
