15.2 Driver Update

In case of a driver update it's not necessary to remove the old driver first, it will be overwritten
during the installation. In case of problems the driver files can be deleted manually by dragging
them to the trash bin:
/Applications/Fireface USB Mixer
/Applications/Fireface USB Settings
/System/Library/Extensions/FirefaceUSB.kext
/Users/username/Library/Preferences/Fireface USB folder
/Users/username/Library/Preferences/de.rme-audio.FirefaceUSBMixer.plist
/Users/username/Library/Preferences/de.rme-audio.TotalmixFX.plist
/Users/username/Library/Preferences/de.rme-audio.Fireface_USB_Settings.plist
/Library/LaunchAgents/de.rme-audio.firefaceUSBAgent.plist

15.3 Firmware Update

The Flash Update Tool updates the firmware of the Fireface UC to the latest version. It requires
an already installed driver.
Start the program Fireface USB Flash. The Flash Update Tool displays the current revision of
the Fireface UC's firmware, and whether it needs an update or not. If so, simply press the 'Up-
date' button. A progress bar will indicate when the flash process is finished (Verify Ok).
If more than one Fireface is installed, all units can be flashed by changing to the next tab and
repeating the process.
After the update the unit needs to be reset. This is done by powering down the Fireface for a
few seconds. A reboot of the computer is not necessary.
When the update fails (status: failure), the unit's second BIOS will be used from the next cold
boot on (Secure BIOS Technology). Therefore the unit stays fully functional. The flash process
should then be tried again on a different computer.
The Safety BIOS can also be activated manually: Push the rotary encoder button while switch-
ing on the unit. This method is also useful to temporarily deactivate a newer firmware. With
pressed button the older version of the firmware will be loaded.
