USB 3.2 Specification Published

Written by Michael Larabel in Hardware on 27 September 2017 at 01:41 PM EDT. 60 Comments

It's been known another USB spec update was being worked on as "USB 3.2" while a few days ago this specification update was made official.

USB 3.2 again doubles the bandwidth to now allow up to 20 Gbps over a USB Type-C cable. This increased bandwidth comes from a two-lane operation mode as well as minor performance work on the hub specification. Existing USB Type-C 10 Gbps SuperSpeed Gen 2 certified cables should be able to support the USB 3.2 specification. The USB-C 3.1 Gen 1 cables meanwhile will be boosted from 5 Gbps to 10 Gbps with the multi-lane mode of USB 3.2.

The USB 3.2 specification is available from USB.org. USB 3.2 devices should begin appearing in 2018.
