Hi,
As a host it is expected that the bus is supplied by the host and this is not possible on XMC4800 Relax Kit.
Regards,
Jesus

Thanks for answering.
Compare the USB on XMC4800 Relax Kit and the XMC4500: only different is pin P0.9 connected to USB pin 4.
If I modify the board, will it work as host mode?

Yes, but further more XMC4800 RelaxKit is designed to be supplied as a device from the USB-bus.
It is not designed and prepared to supply the bus on its own as a host.
You need to make sure, the bus is supplied by the board Pin5/USB-connector (e.g. BAS3010A-03W is hindering you to do so).
And for OTG-support operation the bus supply direction is under control of the USB peripheral. See DRIVEBUS-signal on XMC4500 Hexagon-Kit.
