30.2 Class Compliant Mode under Windows and Mac OS X
On a Windows PC, Class Compliant mode is indicated by a missing “RME“ in the device name
shown in the Device Manager. In the correct mode (PC) and with installed drivers, the full name
including RME is shown, without serial number.
Windows does not support USB Audio 2.0 directly. The Babyface Pro will be detected when in
CC mode, but automatic driver installation will fail.
Mac OS X supports Class
Compliant USB Audio 2.0,
even with more than 2
channels. The Babyface offers
full 12 input and 12 output
channels at up to 192 kHz. It is
shown as “Babyface Pro
(xxxxxxxx)“ in the Audio MIDI
Setup, in both PC and CC
mode. In CC mode the USB
Settings will vanish from the
Dock, and TotalMix FX will not
start, or show a ‘disconnected’
Babyface Pro.
The Audio window in the Audio
MIDI Setup lists two available
modes: 2 channels and 12
channels. The sample rate
shown here as ‘Default’ is the
one set at the Babyface Pro.
Alsa (Linux) does not work with USB 2 Class Compliant interfaces at this time, but it seems it
can be fixed (recompiled) to do so. More information is available here:
