Thomas M brought up an excellent point, which is that USB technology is intended to provide both data transfer AND POWER to the connected device.
So the concept of creating a USB over the air technology doesn’t really work because at best, you could, in theory, convert the usb data protocol over to some kind of wireless protocol, but then how do you address the power requirement of the end device?
Sure, you could make the wireless USB receiver device capable of being plugged into the wall for power and that would only give you an advantage of being able to replace a usb cable with a power supply instead…
From an engineering / product design perspective I can’t see much utility in a USB over the air technology and if you really do need it, then get a raspberry PI and use ‘VirtualHere’ which seems to be a mature and flexible USB over TCP/IP technology that has a wide variety of platform support.
