Dear @idof
Thanks a lot for reaching our technical support.
Regarding your concern, probably you forgot to add the USB Stack and examples of the SDK package you downloaded and installed it. Please be sure to download the full SDK package from SDK Builder, and then you will be able to see many examples with USB Host for different applications.
Please see the image attached for reference and please let me know if you have anything else I can help you with.
