I want to try out dfu-programmer. I downloaded the Windows program from here: http://sourceforge.net/projects/dfu-programmer/files/dfu-programmer/0.7.0/

The command line format I am using is similar to this post: https://www.avrfreaks.net/projects/atmel-dfu-programmer-win32?skey=dfu-programmer
Avrdude works fine. It has no trouble finding the device.
Here is what I get with dfu-programmer:
C:\Downloads\dfu-programmer-win-0.7.2>.\dfu-programmer ATxmega128A4U dump dfu-programmer: no device present. C:\Downloads\dfu-programmer-win-0.7.2>
I tried lower case and that doesn't work either.
My device manager shows this:
