What you need is called a USB Repeater Extension cable, here is the one I bought from monoprice that worked without any issues:
For only $4.27 each when QTY 50+ purchased - 16ft 5M USB 2.0 A Male to A Female Active Extension / Repeater Cable (Kinect & PS3 Move Compatible Extension) | USB 2.0 Extenders
I doubt you'll find it cheaper used from anyone (due to the oddity of it)
