WP76xx support USB OTG function by USB port in LGA(not through HSIC).
When WP76xx act as a USB host role, after plugging in a USB mass storage, you should see that the thumb drive in Linux.
I know managOH green board is ready(has necessary circuit) for OTG function.
However, I don’t know how to check it with Linux.
Could you share some instruction to check(USB device e.g. USB disk or mouse) in Linux?
Also what kind of USB host function are support(build in)? e.g. HID keyBD? USB hub? WIFI(or BT) module?
