New USB 3.0 Specs Promise New Devices, Less Wire Clutter

“The group behind the USB 3.0 specification has announced a tweak which could lead to impressive new devices, including large-format displays, printers, and even laptops that are powered entirely from a USB port.

The third generation of the Universal Serial Bus standard introduced high speeds of up to 5Gb/s, but also added increased bus power of up to 900mA at 5V for more complex devices. This latest update goes a step further, however: allowing variable voltages and up to 100W to be negotiated over USB, the new standard will greatly increase the flexibility of USB devices.

Announced today by the USB 3.0 Promoter Group, the USB Power Delivery specification is designed to co-exist with the current USB Battery Charging 1.2 specification and includes backwards compatibility with USB 2.0 as well as support for USB 3.0.”
