Last week, the EU Commission announced that it's working towards making USB-C the universal standard for charging portable electronics and this week, the USB-IF is bringing new Certified USB Type-C cable and Certified USB4 logos to help consumers figure out what is what. However, the USB-IF is also pointing out that consumers should only buy Certified USB products from trusted sources, suggesting that there are a lot of products in the market that don't meet the various USB specifications.
The new logos can be seen below and the first one is for devices that support 40 Gbps speeds over USB. Keep in mind that although USB4 is broadly based on Thunderbolt 3, the cables aren't going to be exactly the same, but that some USB4 implementations can also support Thunderbolt 4, just to complicate things a little bit extra. This logo can also be used with 40 Gbps capable ports on devices.
