Apple supports using the iPad Camera Connection kit or Lightning to USB Camera Adapter with cameras. You may also be able to use some USB audio/MIDI devices with the iPad Camera Connector or Lightning to USB Camera Adapter. To find out if a USB audio/MIDI device is compatible, contact the device manufacturer. Using the iPad Camera Connector Kit or Lightning to USB Camera Adapter with other USB devices is not supported.

Note: You should only use digital cameras that support the Picture Transfer Protocol (PTP) or USB Mass Storage Device protocol.

If you encounter an issue trying to connect a digital camera through an unsupported USB device, try the following steps:

  1. Disconnect the iPad Camera Connector from iPad.
  2. Disconnect any USB device connected to the iPad Camera Connector.
  3. Restart iPad.
