Any Apple iPad with at least iOS 5. iPhone and iPod Touch can not be used.

Apple iPad Camera Connection Kit (Dock or Lightning to USB)
3. Operation
Activation of the Class Compliant mode: Hold down the Select and Recall button while the Babyface
boots. So press both buttons while connecting the Babyface to USB buspower. The level meters will
run up, confirming CC mode is activated. The Babyface stays in CC mode until this procedure is
repeated. With only one LED on left and right side lit during power-on, the Babyface is in normal
mode.
Connect the USB cable to the Camera Connection Kit. Start the iPad and plug the Camera
Connection Kit into the Dock connector. If everything works as expected, the unit will be used for all
audio I/O. Audio playback in iTunes will automatically be performed by the Babyface, using analog
outputs 1/2 and the phones outputs 3/4, plus SPDIF/ADAT in parallel.
Apps that support MIDI and are ready for Core MIDI (available since iOS 4) will offer dialogs to select
the desired Babyface MIDI input and output.
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 is insufficient, iOS will complain about the attached unit
drawing too much power.
When using hard covers as back panel protection for the iPad, the Connection Kit's plug may not fit
completely, causing a loose connection or partial functionality. If in doubt, remove the cover.
No sound: Incorrect output gain settings, see next chapter.
The iPad's volume control is inactive during USB operation.
If the unit does not enter Host mode:
Remove and reconnect the Connection
Kit.
Correct detection and operation of the
Connection Kit itself can be determined
in Settings / General / About. The
adapter will be listed there right after
connection, with additional details like
manufacturer, model number etc.
Connected USB devices, i.e. the
Babyface will not be shown here,
though.
