Q. Cannot open a port even though installation has been successful.
A1. This is possibly due to the FTDI serial driver holding the port with your VID and PID. Solution is to uninstall
the serial driver (see www.ftdichip.com knowledgebase on how to do this). To completely eradicate the possibility of
this occurring in future it is recommended a new VID and PID is used to distinguish between devices.
A2. Another possibility is an incorrect VID/PID. Try changing your application to use the FT_SetVIDPID API call to
quickly determine if this is the case.
