With the release of the newest Firmware versions from PreSonus Audio, the firmware version 7045/7786/8596 (for StudioLive AI mixers) and 7049/7784/8591 (for RM Mixers with UC Surface) do not have a script enabled in firmware to be able to connect for firmware updates. If you are running this version currently on your mixer, you will need to complete a Firmware Update process for your RM mixer or StudioLive AI Console mixer via USB.
The instructions for these update processes can be found on your My PreSonus account under your hardware registration, or through the links provided below on our Knowledge Base:
StudioLive RM series Firmware Update (via USB thumb drive)
StudioLive AI mixer Firmware Update (via USB thumb drive)
