USB 3.1 Specifications Published, Supports Speeds Up to 10 Gbps

USB 3.0 specifications has been introduced in 2008 with support for up to 5Gbps bandwidth. Although, my PC has two USB 3.0 ports, I’m still very much living in a USB 2.0 world, as I’ve yet to use USB 3.0 peripherals… But progress never stops, and the USB 3.0 Promoter Group just approved the new USB 3.1 specification (PDF file) which can support data speeds up to 10 Gbps.


So after Full Speed (12 Mbps, USB 1.1), High Speed (480 Mbps, USB 2.0), SuperSpeed (5Gbps, USB 3.0), we’ve now got SuperSpeed 10Gpbs (SUPERSPEED+) with USB 3.1.

The standard is backwards compatible with USB 3.0 and USB 2.0, but apparently not USB 1.1. It will also allow for up to 100W to be sent through a USB cable.

If you are a developer, three developer conferences are planned in order to provide technical details about USB 3.1:

  1. USB 3.1 Developers Day US – August 21, 2013 in Hillsboro, Ore.
  2. USB 3.1 Developers Days Europe – October 1-2, 2013 in Dublin, Ireland
  3. USB 3.1 Developers Days Asia – Two day conference scheduled for early December 2013.

Details for registration are available on You can want to go through USB 3.1 specifications, the 37.7 MB file can be downloaded here.

I haven’t read the specification, but I think it also delivers power delivery profiles up to 100W, e.g. 5A 20V. This means we can actually power laptops via USB (if implemented).
