I am using a JLink with PlatformIO in VSCode to debug a sketch for ItsyBitsy M0 Express. The upload using the JLink is working, and I can launch a debug session, the sketch stops, as it should, at the start of "main." The issue I am having is that when the debug session is active the ItsyBitsy USB Serial port no longer appears, so the sketch hangs on the check for a CDC connection. When the debugger is not attached to the ItsyBitsy the serial port works just fine.
Seems I may be missing a configuration here?
