This dongle as supplied by you DOES NOT support AP mode. The above commenter, and I, get it from right here: iw list. I’m stuck with thirteen of these stupid dongles and an embarrassing delay to explain based on what you’ve written on this page.
You are not correct. Stop telling people this supports AP mode until you post a driver that proves it.
