The USB 3.0 Promoter Group on Wednesday added the USB On-the-Go (OTG) 3.0 and Embedded Host supplement to the USB 3.0 Specification. It allows compatible SuperSpeed USB portable devices to communicate without the need for a PC. They can act either as USB host or USB peripheral through the same connection.
The new capability will speed up synchronization or streaming of rich data. The new spec is also more energy efficient than USB OTG 2.0 while being backwards compatible with the older standard.
Before consumers can take advantage of the benefits of USB 3.0 OTG, companies need to begin implementing it into their hardware and ship it first. No one has yet announced any products using the new spec.
