Explains how to disable and reenable USB ports using platform commands, notes the absence of system messages when USB devices are inserted while disabled, and clarifies that Bluetooth dongles are not affected by these commands.

USB ports are hardware interfaces on standalone or stacked devices that:

  • can be disabled together using the platform usb disable command

  • can be reenabled using the no platform usb disable command, and

  • do not generate system messages when a USB device is inserted while the ports are disabled.

The platform usb disable command disables USB ports on the device, but it does not disable Bluetooth dongles connected to USB ports.

Disable USB (CLI)

Disable all USB ports on a standalone or stacked device.

Use this task when you want to prevent USB devices from being used on the device. When USB ports are disabled, the device does not generate system messages if a USB device is inserted.

Procedure

1.

Enter global configuration mode.

Example:

Device# configure terminal
2.

Disable all the USB ports on the device.

Example:

Device(config)# [no] platform usb disable

Use the no platform usb disable command to reenable the USB ports.

All USB ports on the device are disabled. The device will not recognize or generate system messages for connected USB peripherals.
