Isnt this what "USB-IF certified" is supposed to guarantee?

USB-IF certified is a certification that the cable follows the spec, but that spans usb 2.0-only cables up to USB4v2 cables. The tester shows you what the capabilities are.

Yes, there's even a spec here: https://www.usb.org/sites/default/files/usb_type-c_cable_logo_usage_guidelines_20240903.pdf https://www.usb.org/sites/default/files/usb_type-c_cable_log... The cables are supposed to be labelled with their maximum speed (5, 10, 20, 40, or 80 Gbps or nothing if no data) and maximum wattage (60W or 240W). HOWEVER, I don't remember ever seeing a cable with such a label. I'm sure they exist, but I don't see them. Requiring products to be labelled, and treating mislabelling as fraud, could mostly solve this. It's definitely a real problem.

  > Requiring products to be labelled, and treating mislabelling as fraud, could mostly solve this. There are too many manufacturers to hunt. Basically USB-IF needs to stop almost all shipments in the world. That's not going to happen. USB spec is completely open and free to obtain. While it allows people to develop and DIY many things, it also attracts bad manufacturers like flies. Good certified cables with correct markings exist. There are companies like Cable Matters or Startech who bother to actually certify their cables and get USB-IF TIDs. They do cost you quite a bit money though.
