This is what I have.
I would assume that whatever this cable has is adequate as I can control the mount with the ASCOM tools. The issue appears to be more with how PHD2 is interacting with ASCOM. I don't think this is a hardware/cable issue. I can get one that specifically states that it has this FTDI chip, but I not convinced it would make a difference.
