Bad idea... At this point your PIC is possibly damaged. You forced a voltage on a pin used as output (the one feeding the gate of Q2). In case you're lucky, locate the USBID net in the layout and measure its voltage, it should be 0 when an A cable is plugged to the USB jack or when the host mode switch is in the H position.
