USB HOST CDC

Hi

I don't understand how works the example USB_HOST_CDC  included in SDK library for microprocessor LPC54608..

The example run on demo board  OM13092.

I have connected a serial port to connector P4 of DEMOBOARD and I have attached a CDC  serial device on USB0 port  of DEMOBOARD.  I connected the serial TX pin with the serial RX pin of  CDC serial device.

I suppose when I send a single byte through serial port connected to  P4 of DEMOBOARD I have to receive  the same byte on RX serial port connected to P4 of DEMOBOARD. 

I don't receive anything on serial port connected to P4.

What's wrong? How does the example work?

Best Regards

 

Giovanni
