Yea I always use a powered usb hub, unless I connect a small thumb drive or my Korg nanokey controller via Bluetooth. It all depends on the device's power draw. I have a number if USB midi peripherals that don't need the extra power.but my LaunchPad X is unusable without it.and others have reported the same. I have to use a third party charger (and not all work for this) or my MacBook Air's USB out or a 3rd party powered hub. It all depends on the device's power said:Īs I mentioned above, some USB devices use more power than the Camera Adapter will supply if the lightning power is coming from an Apple USB power adapter. I did exactly what you did, had the single port for awhile then about a year ago I upgraded so I can charge as well.Īre you using the same keyboard as OP? If not, your devices might draw less power.Īs I mentioned above, some USB devices use more power than the Camera Adapter will supply if the lightning power is coming from an Apple USB power adapter. I use a couple different brands/sized External HD’s moving files back and forth, midi controllers, instruments/mic through an interface, worked every time. So I am wondering is anyone has encountered problem with this newer adapter from Apple? My Roland A-49 keyboard does not power up with it, my other controllers do work correctly (QuNexus, Korg Microkey Air 25 and Novation Lauchkey).

Wondering if anyone has come any compatibility issues with it? I also had for years the standard lightning to USB adapter (single port)

Just bought one of these today, it has 2 IN ports, 1 USB 3 and 1 lightning so it can charge the iPad while having something connected in the USB 3 port.
