    USBUART dose not ennummerate

    user_396317036

      Hi,

         

      Iam new to PSOC devises. Iam using an CY8C5888 witch is a very cool device. I have played around with the USBUART component and I have noticed a strage behavior. When I plug the USB in my notebook docking station or USB hub then all works fine. But if I use one of the USB ports witch are located in my notebook then the Windows 7 tells my that there is a unknown device. The Vendor PID is 0 and Iam not able to install a driver. 

         

      Dose anyone have a idea what could be the reason? (The USBUART example from the PSOC creator studio dose have the same behavior. )

         

      thanks a lot for your answers!
