Hi

The HS USBs can be used as device or host (and change between the two roles via OTG protocol). One USB interface can never be used as both host or device at the same time.

On devices with two HS USB controllers one can be host and the other device (or both device or both host).

The following shows dual HS USB simulation on the i.MX RT and Kinetis K66 (which has more or less the same USB controller) https://youtu.be/3irORtbc4e0
