Enabling or Disabling the USB Port

The autorun feature only works when a USB device is inserted and the USB port is enabled.

Behavior of Autorun When USB Port is DisabledSoftware Versions K.13.XX Operation

When using software version K.13.58, if the USB port is disabled (no usb-port command), the USB autorun function does not work in the USB port until the USB port is enabled, the config file is saved, and the switch is rebooted. The 5 volt power to the USB port remains on even after the USB port has been disabled.

For software versions after K.13.58, the 5 volt power applied to the USB port is synchronized with the enabling of the USB port, that is, when the USB port is enabled, the 5 volts are supplied; when the USB port is disabled, the 5 volts are not supplied. For previous software versions the power was supplied continuously. The autorun function does not require a switch reboot, but the USB device must be inserted at least once after the port is enabled so that the switch recognizes that the device is present. If the USB device is inserted and then the USB port is enabled, the switch does not recognize that a USB device is present.

Software Version K.14.XX Operation

For software versions K.14.XX, the USB port can be disabled and enabled without affecting the autorun feature. When the USB port is enabled, the autorun feature activates if a USB device is already inserted in the USB port.

Power is synchronized with the enabling and disabling of USB ports as described above for K.13.59 and later software.
