"Inherently meaningless" is fine for a name. Anyway this one has an externally-applied meaning in the form of an actual specification, which defines OTG explicitly: On-The-Go: An OTG product is a portable device that uses a single Micro-AB receptacle (and no other USB receptacles) to operate at times as a USB Targeted Host and at times as a USB peripheral. OTG devices shall always operate as a standard peripheral when connected to a standard USB host. You can get the rest of the details from the specification itself: https://www.usb.org/document-library/go-and-embedded-host-supplement-usb-revision-30-specification-revision-11 https://www.usb.org/document-library/go-and-embedded-host-su...
