Upgrade the USB Hub
I didn't like the usb hub I got because it could only power one unit and not multiple. So i ended up buy another usb hub with external power.
The hub I bought
The problem with this was that the car provides 12v-13v dc and the hub needed 5v. So what I did was take an old cell phone car charger and hacked away. Sorry no detail images on this mod. Just know the 12v is coming from the left (blue - ground, red - 12v) and 5v is going out on the right.
On the 5v out I connected it to the USB Hub power adapter wire to be plugged into the USB Hub.
Chopped the wire from the USB power adapter
The final look
The hub above was too big to be placed in the location I had the old hub so I ended up buying another hub that was more compact and had an external power source and attached it's wires to the car charger mod I did above. So now I have two hubs being powered by the cell phone car charger. BTW I put a .5amp fuse in the inline fuse.
The new compact hub I got from frys: http://www.frys.com/product/5346298?...H:MAIN_RSLT_PG
