Hello Kai,
It is an interesting proposal you make. I totally agree with you, there are many questions regarding USB stack. As for now, we could create a category called "USB" within the Kinetis space since we have tons of USB-related questions but not only for Kinetis platform.
Please let me know if this would help and we'll be happy to create that for you.
That would involve, of course, moving all content in there :smileywink:
Best regards,
Monica.
