EM7565 enumeration

[Tomcsányi, Domonkos]

Hi Paul,

The android path is inside the device, can you do the command
adb shell

and see if you can access the shell? Because if yes you should be able to reconfigure the Android USB gadget to disable ADB.
Also there is probably a way to reconfigure from the host directly.
Can you try the perl script attached to the subpage ‘D-Link DWM222’ of my linked page and see what modes it shows when run?

Cheers,
Domi
