Question

purchased faderport v2, running win 10 and studio one 4, followed the instructions in the manual, the faderport port does not show up as an external device in the midi "receive" and "send to" drop-down options, ..also disconnected all other usb devices besides qwerty keyboard + mouse, this is not working for me.

Answer 1

The Faderport is Designed to work Natively in Studio One 4. 

Take a look at the Setup instructions that are in the User Manual. 

These should get everything working. 

If you still have issues after all that Definitely contact Presonus Tech Support for further assistance. 

Answer 2

Wow, I wish I would have looked at the support site before purchasing a FaderPort v2! I just got it today, October 7th 2018 and when I launched the driver, it loaded Studio One 4 and then said " fader port not compatible with studio one 4" like WHAT? Presonus faderport, not compatible with Presonus Studio One 4 ?????????

That just can't be the case, there has to be an easy answer / solution right??? Running Windows 10 64bit as OS.
