13. Driver and Firmware

13.1 Driver Installation

RME is constantly improving their drivers - the included Driver CD is most probably already

outdated when unpacking the product. Please download the latest drivers from the RME web-

site at http://rme.to/usbe

. Unzip the downloaded file and start the driver installation by double-

clicking Fireface USB.pkg.

If internet access is not available install the drivers from the RME Driver CD, located in the

folder Fireface USB. Installation works automatically by a double-click on the file Fireface

USB.pkg.

Now connect computer and Digiface USB with the supplied USB cable. Mac OS X detects the

new hardware as Digiface USB (serial number).

During driver installation the programs Totalmix (TotalMix FX) and Fireface USB Settings are

copied to the Applications folder. They will automatically start into the dock if a Digiface USB is

connected. A reboot of the computer is not required.

Driver Updates do not require to remove the existing drivers. Simply install the new driver over

the existing one.

Possible reasons why a Digiface USB is not found after driver installation:

• The USB port is not active in the system

• The USB cable is not, or not correctly inserted into the socket

• The Digiface USB does not receive any or not enough power. Remove current-consuming

hard drives from nearby ports. Avoid USB extension cables or USB hubs.

13.2 De-installing the Drivers

In case of problems the driver files can be deleted manually by dragging them to the trash bin:

/Applications/Fireface USB Settings

/Applications/Totalmix

/System/Library/Extensions/FirefaceUSB.kext

/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

Under the latest Mac OS the User/Library folder is not visible in the Finder. To unhide it start

Finder, click on the menu item Go. Hold down the option (alt) key, then click on Library.
