Hi,

   

The shield connection is correct.  Have you tried your hardware on another PC.

 Hi,

   

Shield connection looks good. Please double check your power supply design. AN70707 http://www.cypress.com/?docID=42264 would be helpful. Hope you have provided enough track width for power supply traces.

   

Regards
