Hi all, i have and product consists an USB port. For a reason, we have to modify the line from product to PC to another port (B) as attachment ( i make it in simple circuit). Even though the USB port B not connect or short circuit as i checked, but PC just recognize the USB A if i disconnect the DP and DN signal to USB B ( if i connect DP and DM to USB port B , then windows will pop up "USB malfunction , can't recognize"). Can someone educate me this case ?
