I'm trying to run the example that comes with FreeRTOS and it runs fine. But I have a problem with the USB CDC.

When it creates the task, it creates it with priority 0. And it never runs, it only stays in the READY state.
When I change the priority to 2 it enumerates fine.

Is this right?

PS.: I'm new to FreeRTOS.

Yes, I have posted there. The problem is that we have created a task with priority 2, and it was eating all the resources. This task cannot wait for the others, because it is the main task. It interprets our own PLC language.

I'm using FreeRTOS and their USB CDC example.  Haven't had a problem with using the default priority.  I did remove all the other examples from their project though apart from the LED one (which required some alteration to work with LED2..)
