Disable USB port

Hello,
The USB interface of an AR router cannot be disabled.

Hope to help you!

Performing USB-based Deployment:

Before using a USB flash drive to upgrade or configure a device, make an index file, save the index file to the root directory of the USB flash drive, and save files to be loaded to the directory specified in the index file. Then connect the USB flash drive to the device to start the upgrade process.

Note: I think there is no way to disable USB port on AR

Hi,
The USB port is mainly used for the USB-based deployment function. By default, the USB-based deployment function is disabled. As long as the device has any configuration, it will not read the file from the USB flash drive. So the USB interface does not need to be disabled.
