32.1 Useful hints
If the unit is not in CC mode, the iPad will detect an
incompatible USB device, and display a message saying
“Cannot Use Device – The connected USB device is not
supported”.
When the power supply for the Babyface Pro is insufficient, iOS will complain about the at-
tached unit drawing too much power.
The iPad's volume control is inactive during USB operation.
If the unit does not enter Host mode: Remove and reconnect the Connection Kit.
Since 2016 Apple offers another version of the USB to Lightning Adapter, called Lightning to
USB 3 Camera Adapter. It has an additional Lightning port for power supply that charges the
iPhone/iPad even when used with the Babyface Pro.
32.2 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.
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 Set-
tings will vanish from the Dock, and TotalMix FX will not start, or show a ‘disconnected’ Baby-
face Pro.
The Audio window in the Audio MIDI Setup lists two available modes: 2 channels and 12 chan-
nels. The sample rate shown here as ‘Default’ is the one set at the Babyface Pro.
