New Board, Dead USB port

[skineedog]

I just received and installed a new 250c board today. After finally getting everything assembled, I find that the usb connection is very loose and neither the board nor the computer respond when connecting to USB. By loose, I mean the cable connection to the port and not the port on the board itself. I have tried several known good usb cables with no response. Has anyone had similar experiences? Is there something I can do to troubleshoot? I have already submitted a ticket to Evolve, but thought I'd check the forum in the meantime.
