UART to USB Bridge - CP210x

I'm using the built in CP2103 UART/USB bridge on the ML628 board but am having issues with IO. I'm trying to send 9600 baud, 8 data bits, 1 stop bit, no flow control. I have the drive installed on the computer and am using Hyperterminal/Putty to listen.

 

I'm sending the board's TX signal out to the USB_RX pin and have the RX signal connected to the board's USB_TX pin.

 

I cant see any successful communication with both send and receive.

 

I routed my desired signal to an external IO pin to view it on a scope and made sure the data looks good.

 

Not sure what the problem could be.
