A USB device uses a controller to talk to its host.
Systems should have only one such upstream link.

+ A Linux "Gadget Driver" talks to the USB Peripheral Controller

+ Gadget drivers are hardware-neutral, or "platform independent",
+ except that they sometimes must understand quirks or limitations
+ of the particular controllers they work with. For example, when
+ a controller doesn't support alternate configurations or provide
+ enough of the right types of endpoints, the gadget driver might
