Mvdj 4000

I ordered the mvdj 4000 it came with mixvibes 2.2 le. I installed the software with no problem. When I plugged in the device with the provided usb cable it seemed to download the driver just fine. When I open the program the hardware will not work. In the device manager it recognizes the unit as MIDI 8s, but the model number and the manufacturer are unknown. Could it be defective? Do I need a powered usb hub? Any advice would help. Joek818@gmail.com
