i researched some more, and i can't use the hub unless i already have a usb 2.0 connection. so i need to use a pcmcia card with 4 ports and prolly power that off the inverter. maybe something like this, but maybe i can find one cheaper that will solve my problem. something like this won't have a prob powering this http://mystorix.com/optical_idx.html or will i be better off running my laptop, pcmcia card, and dvd drive off the inverter?
