How can I add USB3 support to a Ghost Boot Disk

Hey guys,

I'm trying to add  the drivers for a USB3 device using the storage drivers section of the Ghost Boot wizard, but when I select the folder with the drivers, it says it did not find any drivers in that folder.

By tyhe way, I want to add USB3 because I want to use an external hard drive to create the image into.

What can I do?

Thanks
