Option

Description

host

Becomes the USB bus host on the OTG port. Once it becomes the host, it enumerates any device

 

connected to the host on the OTG port

idle

If the OTG device is the bus host on the OTG port, de-enumerates the connected USB device and

 

comes out of the bus host.

load

Loads OTG modules

unload

Unloads OTG modules

mount

If the OTG device is the USB bus host on the OTG port and the connected device is a mass storage

 

device, mounts both the local OTG device disk and the remote OTG device disk to the mount points.

umount

If the local OTG device disk and the remote OTG device disk are mounted to the mount points,

 

unmounts both these devices.

status

Current state of the OTG port and the OTG device disks mount status.

help

Prints help menu.

To operate the OTG mass storage device as a host, connect the other OTG mass storage device through the OTG cable and execute the following on one of the targets:

1.#./otgcmd host

This command will make the OTG mass storage device as a USB host on the executed target.
