Then you have do a lot of things in this forum
Your device work properly, your connection cable is good, you don't connect any Tx and Rx with other cable, than you still have a problem this is the best solution but you still frustrated :b, it is because

when you install the driver of FTDI, there is still a   Virtual Comp like this:

But when, In my case I have USB Serial Converter, then I delete the  USB Serial (COM3)
