Question about Apple Lightning USB 3 Kamera-Adapter
Is it possible to connect an adapter to 3.5mm jack to the Lightning connector in order to connect headphones in addition to USB? I would like to connect a MIDI keyboard via USB and output the sound to headphones. Unfortunately, there is too much delay via Bluetooth. Or is the Lightning connector only for the power supply?
Helpful answer
At least when using my iPad Air 2, the Lightning port on the Lightning to USB adapter seems to be there only to connect the power adapter of the iPad so that the power supply is guaranteed - otherwise the iPad complains. The iPad even complains to me when I connect an externally powered USB midi interface to the Lightning to USB adapter in case the iPad's power adapter is unplugged - so even then, you can't use the Lightning connector for anything other than power. On the other hand, when using the Lightning to USB adapter AND the power adapter of the iOS device, an active USB hub can be connected (i.e. a hub that is powered externally). Thus, several USB devices, e.g. a USB midi keyboard and USB audio interface, can be connected and used simultaneously - and everyone is happy, lalala. However, a product specialist may be able to answer this question better than I can...
Unfortunately it doesn't work... I tested it with iPhone and iPadMini. As soon as you connect the Lightning to 3.5mm jack adapter to the Lightning to USB adapter, the message "Accessory Not Supported - This Accessory is not supported by this device" appears.
I tried this briefly with my iPhone XR. The result is the same as with Wolkensprung, no sound is output to the headphones. Seems to be really only good for the power supply.
