The gadget API is the programming API offered by the kernel for the OTG

More importantly, the USB ports which support OTG are driven by
different hardware.
Ah, so the hardware has to play along...
Right, you need both your hardware's USB port to support OTG and you
need your kernel to have a driver that supports this hardware.
AFAIK the driver is usually available.
Did I say I was handwaving?
Thanks for the clarifications!
It also suggests that I frequently grasp some of the implications of
what I read. Thank you.
As an illustration of my mindset:
If they had really intended USB to be *UNIVERSAL* serial bus, then it
should have been OTG from the get go.
P.S. I know of thousands of reasons they did not.
