Part Number: TUSB8020BEVM

This eval board is detected as "Generic USB 2.1 Hub", even the host port where is connected is USB 3.0. (USB Device Tree Viewer attached).

I connected this device to two different computers running Win 10, and I had the same results.

Any help will be appreciated.

  • Hi Jorge,

    Please resend the attachment, it did not come through.  The hub should connect as both a USB 2.1 and USB 3.x hub simultaneously.

    Hi Jorge,

    The hub connected to Port 21 in the screenshot will be the USB3.x instance of the TUSB8020BEVM.

    I can see... I just reset the USB port and Port 21 is not there anymore (see attached)

    Hi Jorge,

    How did you reset the port?  If the host leaves its rx terminations and VBUS on during a reset the hub may enter compliance mode, you will need to reset the hub to exit this mode.

    I reset the port by unplugged/plugged the USB cable that is coming from the host computer.

    At this time I reset my computer a couple of times, and try different HUB reset, and there is no way that I can see that Port 21 anymore.

    Additional info: I also have a TUSB8041 eval board, and it is doing the same issue.

    Hi Jorge,

    Can you send me a screen shot of the TUSB8041 connected?  And the hub doesn't show up after hitting options -> refresh?

    What length cable is being used?  Is it Type-C on one side?
