DO NOT follow the instructions regarding the Vysor dongle
For some reason the developer disabled the GitHub issues for the repository, so all of the searches for issues regarding this thing lead to 404 pages. This is super annoying. You can still view the cached pages in the Wayback machine, and it looks like a lot of people are having the same problem. When you flash the firmware onto the USB dongle, it will work only while it is plugged in for the first time. It will not work again after that and the dongle doesn't even appear in the list of usb devices attached to your computer.
Works fine with Android devices without the dongle, but that's not why I'm writing this review.
