This accessory is not supported by this device

Port is clean, IOS is up to date and only using certified Apple products that came with this iPad. Didn't ever see this until the last update (as I recall). Best part s that it pops up when nothing is connected. I even turned off Bluetooth.

Hello,

If an alert says that your accessory isn't supported or certified

These alerts can appear for a few reasons: Your iOS device might have a dirty or damaged charging port, your charging accessory is defective, damaged, or non Apple-certified, or your USB charger isn't designed to charge devices.

1. Remove any debris from the charging port on the bottom of your device.
2. Restart your iOS device.
3. Try a different USB cable or charger.
4. Make sure that you have the latest version of iOS.
5. Contact Apple Support to set up service.

Hi. Is it being caused by your Smart Keyboard? If so, take a look at this thread, link: iPad Pro Keyboard "This accessory is not supported by this device". You may want to take it to an Apple store for checking.

I have a genuine apple 30pin to lightning "A1468" adaptor (sourced from Amazon) and my friend has a short cable equivalent (MD824ZM/A) and we have both suffered frequent incompatible accessory warnings since the recent iOS upgrade. My connectivity is to an Alpine car head unit and causes the input to lock out with an Error - 01 which cannot be cleared without a full power re-cycle of the stereo (stereo fine on radio or disc). More often than not the recycle fails to resolve the situation. If I unplug the A1468 lightning adaptor and (iphone) and connect with the 30pin cable to a classic iPod it has zero issues (ie no HU errors)

My friend has a brand new X and I have a 6S. Both appear to have been affected since the software upgrade to 11.2

It cannot be a coincidence surely?

What you have stated here is so true! My device and non-official charging plug worked just fine - until the latest update. My OS was updated a day ago, and now my iPad says, “This accessory may not be supported.” Well, it was supported before the update!

Hi Diana,

I tried the keyboard on my wife's iPad and found it dint work on hers either. Took it to Apple Store where it was replaced. Apparently a known condition.

Thank you for taking interest.

I have this problem as well. They have sent me 4 phones now with the same error when I plug in the accessory adapter and also bought 2 other types of compatible adapters.

Last week I even bought Beats and still get the same error message. I'm very disappointed and annoyed.

I have this issue as well and it comes up out of nowhere, even when nothing is connected to it, been this way for months, thought iOS 11 would make it go away but it didn’t I have the keyboard but rarely use it, Apple charger that came with it...nothing makes the error go away. This is a gen 1 iPad Pro my second one Apple replaced one mont after I had it because of another issue. Could really use some help it is super annoying...thanks

Yes well, I have to be very careful in how I write this reply because it seems that anything critical or negative about Apple gets deleted straight away. I can safely assure you that all but one of the above suggested points is the actual culprit, and that is utilising a non-genuine lightning cable.

I have 5 different devices at home... two iPad 2's, an iPad Air, an iPhone 5, and an iPhone 6 Plus.

And I can tell you from my technical analysis and testing of the above error message across the different devices, is that it has nothing to do with the hardware (being the device or the cable). It is unfortunately an incompatibility of the later iOS software that renders non-genuine cables useless. Older devices that are not upgraded to the latest iOS work perfectly fine with the non-genuine cable.

As a suggestion, I would go to your nearest retailer and purchase a genuine cable. How comfortable you feel doing that (and any reservations felt in needing to do so) I leave to you.

I'm getting the same error when both my iPad mini and iPod touch are docked in my Orbitsound sound bar through a genuine Apple adaptor. Both devices were fine until I installed 11.2 and now both give the same error. I agree, this looks like a bug introduced in that version.

I am getting the same error since updating to iOS 11.2.2 when plugged into the Apple Lightning to 30 pin adapter (the square block without a cable), which is plugged into a (Griffin or Belkin) 30 pin Car charger with line-audio out.

If I plug in after the key has turned to provide current, it doesn't produce the error. If I plug in when the car is completely off, the error occurs when turning the key.

Even with the errors, it still passes audio and power through.

I have tried every trick provided by Verizon and google support.

Hi LaQuitsha. Is your iOS up to date?

What model iPhone is it?

Are the adapters made by Apple? Can you identify them?

I went to the Apple store today and replaced the adapter and now problem solved. My adapter was not an apple adapter and the generic version will not work. My puppy chewed my original adapter.

Hi stephen n. When you say nothing is connected, not even the Smart Keyboard? Many users have this problem with the Smart Keyboard.
