This seems like kind of a strange place to do this restriction. All that the
ExperimentalUsbCustomBindings module does is provide for unique event id's,
similarly to several of the other bindings files listed here that you haven't
ifdef'ed out (ContextMenusCustomBindings, etc.)

Would it not work to just ifdef out the relevant parts of the USB API
implementation in chrome/browser/extensions/api/usb/?
