Determine the speed of a USB Device RRS feed

  • Question

  • Hello,

    I want to determine the speed of a USB-Device. I also need to determine the vendor and the product-ID of the device.

    Can anyone introduce me how to do this?

    Thanks,

    Ralf

  • Hello,

    You can use WMI to do that, here is an example.

  • I think I can't use WMI, because I want to know if the usb port can use lowspeed, fullspeed or highspeed. I haven't found a property at WMI, that gives me this information

  • What about NegotiatedSpeed in the Win32_USBControllerDevice class?

  • Download the DDK.  Ask further questions in the Windows Hardware WDK and Driver Development forum.

  • Hi reden1,

      Welcome to MSDN Forum Support.

      Based on the conversation listed below, I make clear your requirement is to implement usb speed changing between  lowspeed, fullspeed or highspeed. I agree with JohnWein's suggestion to post its similar question at  Windows Hardware WDK and Driver Development forum.

      Sincerely,

      Jason Wang
