SuperSpeed USB has the backing of many major desktop makers and allows power transport as well as data transport, an advantage over Wi-Fi and other wireless, said Jeff Ravencraft, president of the USB-Implementers Forum.

Saunders and Ravencraft said USB will continue to co-exist alongside Wi-Fi and other wireless connections for a long time, as many users continue to prefer a wired connection for very large data data transfers using devices such as high-capacity hard drives.

The USB trade groups are also backing a new power delivery specification, USB Power Delivery, that was first announced last July, The standard aims to reduce the variety of chargers used for smartphones and tablets, Ravencraft said.

Ravencraft said the European Union's requirement enacted last year to have a common charging port (via micro USB) on smartphones instead of different ports specified by different smartphone makers.

Ravencraft said a common charging port is seen as reducing waste in landfills when charging cords become obsolete. He said after the power delivery spec was published last summer, that manufacturers will be developing chips in 2013 to accommodate it.
