We made our own develop board refer to cypress official FX3 development board.But the OS can't detect our board.

   

At first,we configured PMODE to F1F,and we can see CYUSB3014 read something from IIC port after reset,but nothing happened after that.

   

Then ,we  configured PMODE to F11,but still nothing happened after reset.

   

What wrong with it ?We tried to connect to USB3.0port and USB2.0port,but both of them dosen't work .

   

I did not use FX2 before.Who can help me ?

   

Thanks.

Did you connected the 32kHz crystal oscillator on your board? There is a bug in the silicon. If there is no 32kHz clock, the USB is not working: http://www.cypress.com/?app=forum&id=167&rID=54150
