Hi @maaamcube ,

thanks for the feedback.

The commit you have referred to contains the adding of downstream ports logic only.
Basically, these changes is crucial for external Hubs to work.

The enabling Hubs support feature in the USB Host examples itself though has been merged internally and will be available in public soon.
