To my understanding both host mode and OTG mode could be supported by the hardware. Jumper J17 on https://www.microsemi.com/images/10/MicrosoftTeams-image%201.png. USB device mode selection - Open: USB client. Closed: USB host Is OTG really the most important scenario for running the board? I personally would prefer to run it in host mode to add more peripherals. What is missing on the driver side to enable host mode? Can we detect the 5 Volt jumper setting via GPIO?

The usb on icicle kit is actually configured for otg, not host mode. Swap it over.
