USB Promo Group Unveils USB 3.0 On-The-Go Spec

From X-bit Labs: The USB 3.0 promoter group has announced availability of the USB On-The-Go (OTG) 3.0 and Embedded Host supplement to the USB 3.0 specification. The USB 3.0 OTG spec enables portable SuperSpeed USB devices to communicate among themselves when a PC is not present.

The supplement ensures that mobile devices such as phones or cameras are able to use a SuperSpeed USB link in both USB host and USB peripheral roles through a single receptacle. OTG and Embedded Host Devices requiring fast synchronization or streaming of rich data will benefit from this feature.

The USB OTG 3.0 and Embedded Host supplement offers power saving features equivalent to those available in USB OTG 2.0, enabling the adoption of SuperSpeed USB in mobile devices. Additionally, USB OTG 3.0 provides backward compatibility with USB OTG 2.0.
