New USB 3.2 Spec Will Double Data Rates Using Current Cables

The USB 3.0 Promoter Group today announced the upcoming release of a USB 3.2 specification, which is “an incremental update that defines multi-lane operation for new USB 3.2 hosts and devices.” 

According to a statement, new USB 3.2 hosts and devices can now be designed as multi-lane solutions, allowing for up to two lanes of 5 Gbps or two lanes of 10 Gbps operation. By doing this, the new specification is “effectively doubling the performance across existing cables.”

The USB 3.0 Promoter Group is comprised of Apple, HP, Intel, Microsoft, Texas Instruments and other tech companies.

Key characteristics of the USB 3.2 solution include:

  • Two-lane operation using existing USB Type-C™ cables
  • Continued use of existing SuperSpeed USB physical layer data rates and encoding techniques
  • Minor update to hub specification to address increased performance and assure seamless transitions between single and two-lane operation

“When we introduced USB Type-C to the market, we intended to assure that USB Type-C cables and connectors certified for SuperSpeed USB or SuperSpeed USB 10 Gbps would, as produced, support higher performance USB as newer generations of USB 3.0 were developed,” said Brad Saunders, USB 3.0 Promoter Group Chairman. “The USB 3.2 update delivers the next level of performance.”

More information about USB 3.2 will be announced later this year at USB Developer Days 2017.

  • Bring back USB power-on feature from USB keyboard or USB device. As possible with former Apple ADB and USB keyboards, as well as USB dongles with USB 1.0 specifications, like the i-Cue.

    That is extremely useful and convenient to turn on the computer when it is below or behind the table/desk or far away from reach in the floor, etc. It is even a health issue (backbone health!).




  • Thunderbolt 3 supports 20 Gbps per lane using active cables (40 Gbps total), so maybe USB 3.3 will support that in the future? Maybe not, since it will be too much like Thunderbolt then (requiring different cables, etc).

    A USB-C hub cannot also allow DisplayPort if two lanes are being used for USB? Maybe a USB-C hub can switch between 2 lane and 1 lane operation to allow DisplayPort?

    Well, USB+DisplayPort is kind of fail anyway because it allows 4K at only 30Hz.
