    Debugging USB on psoc 4200L

      I've iterated several hardware designs but everything I try leads to a code 43 error. I'm using osh park to manufacture the boards. Using Saturn PCB design I've calculated the impedance width of 45 mil. I've included my design files. What do I need to change to get it to work appropriately? 

         

      The only time I've had any success is when I do not copper fill the entire board and route the traces without any tvs, resistors, or capactors attached. Yet without the tvs, its functionality lasted only a couple of hours before it was no longer functional. Thanks for the help.
