回复至：USB connection (No Tethering)

[spacedesk Lea]

Hi @raya2,
Currently, spacedesk does not support native USB connection between Windows primary machine and Android viewer app.
But you might want to try connection via Android Debug Bridge Cable.
This connection requires you to download the Android SDK platform tools on your primary machine before you can setup an Android Debug Bridge Cable connection.

Please check Android Debug Bridge Cable chapter in the user manual https://forum.spacedesk.netuser-manual.
