C.5 - VDIP Control

The C.5 pin controls the status of the VDIP usb host module. Logic 1 turns on power which switches the VDIP Off! During power on and reset of the VDIP module, this pin should be in the desired state. (The C.5 pin is connected to the RTS line of the VDIP module.) The reason for controlling VDIP status is that the VDIP module uses a shared serial port(FFUART on Gumstix), so having the module switched Off ensures no interference on the shared serial port.
