Hi I bought a few of these thinking they were the same as the ones I had previously bought. They are Cheep about US$4
These did not work automatically when I plugged them in. After a little investigation I found they detect as a 16M usb drive and you need usb_modeswitch to get them to switch to being a wifi adapter.
To make them work install Addons > System Tools
This adds the usb_modeswitch command to coreelec.
Then add the following to the autostart.sh in the config directory
#!/bin/sh ( usb_modeswitch -KW -v 0bda -p 1a2b ) &
Reboot and the device will be detected as wlan1
This was using the internal wifi A95X 2.4G
This is using the external adapter 2.4G
This is using the external adapter 5G
