    KY8KIT-059 USB Shield Not Connected

      The schematic shows that the USB Micro-B receptacle shield should be connected to the board's GND by way of a 100K resistor and 0.01uF capacitor in parallel. All my copies have no solder in the receptacle mounting holes that would make this connection. Once I add solder myself the components test present.


      It doesn't make much difference because 3 of the 4 USB cables I tested don't have a shield.


      I'm trying to determine if the RC connection is best, or direct connection of the shield to GND is better. Both are recommended by skilled designers. I haven't seen anyone recommend open-circuit.
