Wolverine Ultimate, USB Extension

I am really interested if purchasing a Wolverine Ultimate for my Xbox. The only problem is I need about 20’ long usb cable (that includes slack to allow it to lay on the floor to where I sit). I know the controller comes with a 10’ cable, which obviously is t long enough for my situation. I will also have a mic attached for chat. can anyone here recommend a usb extension for this? I assume I will need an extension with a repeater or active extension. Would it be better to get an extension with external power or one that uses bus power? I was looking at the Tripp-Lite U330-5M. This one uses bus power and supply the connected device with 770mA. Any feedback/comments with this is greatly appreciated.
