You’re getting a lot of “hot take” and sarcastic responses, but the actual answer is that they do. To use any of the USB-IF logos (including the official ones that clarify power and signal compatibility) a product has to go through the certification process: https://www.usb.org/logo-license https://www.usb.org/logo-license USB-IF also maintains a list of products that are certified: https://www.usb.org/products https://www.usb.org/products The question then is, “Why is this still confusing?”. The answer is probably that the popular retail and e-commerce channels are flooded with products that aren’t certified, and consumers don’t realize that a certification process even exists.
