CCS/MSP430F5308: MSP430F5508 USB not detected

Part Number:MSP430F5308

Tool/software: Code Composer Studio

Hi,

We designed a board based on MSP430f5508 micro controller. we use USB in our design to talk to the Host PC. USB device is not detected by the host.

We ran you sample code co_simple_send as well from usb developer package. 

Can you please guide us to resolve this issue ?

Thanks
