vikrampant: The point was that what you are suggesting is what he used to do, however he doesn't have an extension cable for use in the current car so it won't reach, which is why he needs to use the hub. In his original car he has a dedicated extension cable to do exactly what you said.
Good point about checking power consumption though. It's only a "rough" number based upon what the USB device tells the hub that it needs, not based on actual current being used, so treat it as a "max" number.
The USB sound card probably takes the full 500mA, my corded optical mouse takes 100mA and the LCD probably uses the full 500mA as well, which means very bad to put them all off the same port without supplimental power.
