Sir i do just like you said solder all three cmd,data0,clk forgetting the two power and plug usb but nothing not connect ... Does it need pullup resistor? One thing i notice is is it normal to detect spd port when i plug usb..? There is spd port in device manager when i plug the device is there something short or its normal
