I want to use USB port on LPC4357 as USB serial host and communicate with FTDI chip via FT232R USB UART.

I use nxpUSBlib, CDC class for communicate. At the enumerate process, the usb lib return that it’s is not valid CDC device when it read the device descriptor.

 

Is CDC Class host is the right way for communicate with FTDI USB UART chip and if it’s not, which is the correct way for using NXPUSBlib

to communicate with FTDI USB UART chip?
