    Would not the speeds between 12MB/s or 480Mb/s be detected by hardware. The termination decides speed capability.

      Nope. Whether HS or LS is determined by the polarity of the data lines. The JKJKJK sequence is used to synchronise the clock, but the overall speed of the communication is determined at the beginning.

      @@_a_x_s_ I recollect USB2.1 having a termination resistance decide the rate of data transfer. Thank you.

    it would be better if you show which part of the signal you were talking. The video almost has not helped your narration.
