Could you please test SDK demo usb_device_cdc_vnic? The purpose of this demo is to show
how to build a device of USB CDC class to implement RNDIS protocol and to provide a simple project for further development.

Thanks,

Jun Zhang

@rijn 

    The attached project is a simple demonstration program based on LPC54018/SDK/usb_examples/usb_device_composite_cdc_vcom_cdc_vcom.
It is enumerated as one RNDIS network port and one virtual COM.
This demo is to show how to build a composite USB device and to provide a
simple example for further development.

   I tested the demo on WIN10. It works fine.

IDE: KEIL

HW:LPC54018 EVK + FS USB port
