    Transfer commands with EP0.

    gleb.levitskiy

      I want to send commands to my device using EP0. But when I try to transfer any data to EP0 in USB Contorl Center it return:

         

      CONTROL OUT transfer
      CONTROL OUT transfer failed with Error Code:997

         

      What this mean?

         

      How I can transfer commands for driving my device? I want to do it same as Class-Specific Requests in UVC.
