Thanks for the info, I didn't know how compiled-in modules behave.

Sure, I wouldn't forget that.
I also accidentally checked the FR's resistance to stupidity by connecting it to a wall charger in host mode. I expected it would switch back to device mode after reboot. Luckily, it still works.

It shows both the line for USB hub and the device. I'd be in trouble if it didn't.
