In KSDK 1.0, there was a USB Device demo for a CDC Virtual Com port. It could be built using a variety of RTOSes, including MQX. This demo doesn't appear to be available in KSDK 1.2 except for a bare metal version. I need an MQX version. I've been trying to cobble this together myself for a day, but to no avail so far. Can anyone help? I'm working on a FRDM-KL43Z.
