      I am using a PSoC cy8ckit-050 to control a semiconductor test system through a USB cable. The PSoC and the tester are operating well through port ‘COM9: ’. It was decided that the LCD display component was not needed and should be removed. I made a copy of the project and removed all references to the LCD component. The project compiled without error, but when I programmed the device, the Windows 10 Device manager reported the removal of COM9: and that an “ Unknown USB Device (Device Descriptor Request Failed)”, was reported.

       

      I also tried programming a PSoC cy8ckit-059 using a USBUART component and no LCD component and had the same failure, compiles and “ Unknown USB Device (Device Descriptor Request Failed)”.
