Hello. I have tried to launch 3 example projects in MCUXpresso IDE called composite_cdc_vcom_cdc_vcom. Description say that:

The demo echoes back any character it receives.

But i see only 2 COM ports appeared and no echo characters if i send data to them. I have looked more closely to project and see that vcomInstance->startTransactions always 0.

Tell me please are example project correct and have tested?

Hi

Try one of these to verify the HW (and the PC); they all contain composites with CDC:

See the following video for dual-port USB device/host simulation:

In case of difficulties with the standard examples you can fall back on the uTasker project as industrially proven USB-CDC solution.
