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

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?

Best regards

Heinrich
