- WwalshrogerAug 19, 2025
If your AMX Touch Panel's USB driver shows a yellow exclamation point, it indicates an incorrect installation. To reinstall the driver: * Power up the panel without the USB cable connected. * Plug in the USB cable. A USB icon should appear in the System Tray. * Double-click the icon to see the "AMX USB LAN LINK" device. * If the "Install Driver" dialog doesn't appear, select "Properties" then "Update Driver." * Click Next on the Install Driver dialog to accept defaults. * Ignore the digital signature warning and continue the installation. * The exclamation point should disappear after installation.
