USB Emulator

I now have uploaded files to the Flashair card in my 3D printer and just warming up to print. (Actually printing now !)

It was a bit of a struggle, but this is the way I have done it :-

The flashair card was updated to the latest firmware and set to AP mode and the alternative web page according to the instructions in
https://mattshub.com/2017/04/11/flashair-sd-card/. Then I used a WIFI USB dongle to connect to the SSID broadcast by the card, in a computer with a wired connection to my network, so I could access my 3D printing files on a NAS drive.

All a little Heath Robinson, but it works and I don't have to keep farting about swapping the SD card between the computer and the printer.

It should be possible to do the same with a USB connection, just using a SD reader plugged into the USB port.
