The FaderPort 8 is "class compliant" meaning it does not require a driver to function.
However PreSonus is committed to continually improving the quality of the FaderPort 8 and its functionality and thus will periodically release firmware updates for it.
The FaderPort 8 can receive firmware updates via the UC app which can be found on the FaderPort 8's Downloads Section.
Simply download and install UC for either PC or Mac from the link above, connect your FP8 to your computer via USB, open UC, and the application will inform you of, and execute, any necessary firmware updates.
Please contact PreSonus Technical Support by creating a Support Ticket at My.PreSonus.com for further assistance.
