No performance testing is done on USB certified devices

YOU MIGHT HAVE noticed a little USB logo on most, if not all of your USB devices that tells you what kind it is, be it bog standard USB, Hi-Speed or now SuperSpeed USB. During today's USB-IF developer's conference we put forward the question to the USB-IF, which is the organization behind these logos that certify that your device is USB compliant, with regards to performance testing and what the requirements are.

We were slightly taken back by the answer. The USB-IF doesn't perform any kind of speed testing at all. For a device to carry the USB logo and get certified, all that is required is that the device meets the interoperability standards and a few other things. Part of the reason for the question was that we're seeing various motherboard makers touting that they offer the fastest and best implementation on their motherboards and we wanted to see what the USB-IF had to say about it.
