On my new PC - Win10 professional - I just connected my Faderport with my computer and it worked plug’n play. I only copy the Faderport.dll to the right place ( C: \ Program Files \ Common Files \ Steinberg \ Shared Components - as shown above) and that was all I have to do.
No Firmware-Updates or Faderport- or Univeral-Controller-Software is needed.
The Presonus Faderport could then be found in the device menu etc… All as descript in the posts above.
