At first; sorry for my bad English, i'm from the Netherlands :D

I have a problem with my iMac 5K and applecare doesn't know how to fix, so i thought you guys may know the answer

I have a 5K iMac since 1,5 month and it connects/disconnects with ALL my iPads ( 2x iPad mini, iPad 3 + iPad air) But my iphone 5 and 6 are connecting FINE.

When i put the USB lightning ( or 30 pin cable with my iPad 3) directly in the USB port ( no hub) the iPad charging icon begins to flicker/blink and connects/disconnects rapidly so i can't sync my device in iTunes. I also have a macbook and an 2010 iMac and the iPads work fine with these 2 computers, the problem only occurs with my iMac 5K


When i plug them in my new iMac 5K it keeps bleeping like a maniac and connecting/disconnecting and i get a warning that i should reset all my permissions. I did what many said in other topics and reset the permissions and even did clean installs on ALL my iPads, but that didn't work. ( also PRAM reset on my 5K) Also it's not the cable because all my devices work on my older macbook/iMac. Also the iPad 3 and mini/air have different cables ( lightning vs 30 pin) and i tried 3 different cables


I think it is the USB port on the computer that doesn't work properly ( i tried ALL USB ports in my new imac without a succes) And it only occurs with my iPads who need more power then my 2 iphones. I think it's the computer


So to be clear:

- it's not the lightning/USB cable ( i tried 3, and they all had the same problem, and the devices work FINE with my old macbook and iMac)
- i clean installed ALL my iPads from scratch.
- i connect the devices directly in my iMac 5K, and don't use an USB hub.



The problem is discussed in more topics, but never had a clear outcome

I have. iMac 5K plus iPad Air 2 that does it on occasion (with the original cable that came with the iPad). Quitting iTunes, disconnecting the iPad plus cable and then hooking everything back up works. I'm guessing that iTunes might be an issue here.

No one with this similar issue?

The problem you describe is the same as plugging an iPad in to any charger that doesn't produce sufficient power to charge an iPad. The blinking, rapid disconnecting/reconnecting and no charge actually occurs. The USB ports are not supplying the power that they are supposed to, something is wrong with your machine's hardware and needs repaired. I would recommend you take the machine in for repair. If Apple can't repair your machine they will replace it.

No it's not the itunes. On my old Macbook and iMac the same version of itunes is installed, and the problem doesn't occur on both machines, only my iMac 5K, it's not the software or power cable

I think you are quite right that this is a sufficient power charging problem because it rapidly connects/disconnects and is in the iMac's hardware. What i find quite strange is that my iphone 5 and 6 will connect but only my iPads ( iPad 3/mini/Air) won't connect and ''blinks/bleeps''. I know that they ask more power but still.. My external HDD that i use for time machine asks the same amount of power or even more and connects perfectly

There's nothing strange about it. Your machine is supplying sufficient power for the smaller iPhone devices and insufficient power for the larger iPad. The hard drive works because it's power draw decreases as the drive spins up to full speed. The iPad draw is continuous. You want get the machine fixed while it's still under warranty, otherwise a logic board swap could be quite costly.

The Lightning cable is simply a USB2.0 cable and USB2.0 does not officially support higher currents than 500mA. The iPad requires about 2A (4x more) so the ports output some extra current (1600mA is what I'm seeing on my iMac thus 2.1A in total).

If you've read carefully then you'd have seen that there are 3 hardware components at play:
  • iPad
  • cable
  • iMac
Next we have software components:
  • OS X
  • iTunes
  • iOS
And finally we have the problem description and the YouTube video that both show something that has got nothing to do with power whatsoever. The issue is with connecting and disconnecting. If you look at the logs you'll find error messages from iTunes where it finds the iPad and then loses the connection. The YouTube video also shows this. When there isn't enough power provided to the iPad it simply stops charging, the connection with iTunes will NOT be lost. There also is no need for the right amount of power via USB, the iPad can be connected to a port that doesn't provide enough power. When connecting the device to such a port it will tell you the charge and then it will say that it is not charging in the top right.

The shown behaviour looks a lot like the behaviour USB2.0 devices show when being put on a USB3.0 port. In some cases it doesn't like the USB3.0 port and will start acting very strangely like connecting and disconnecting rapidly. Using a USB2.0 extension cable or hub between the device and the USB3.0 port is a good workaround. There are issues with USB3.0 ports not going into USB2.0 properly (simply put).

It seems that my iMac is suffering from this problem. I have another USB3.0 dock with integrated hub connected to the iMac. Any USB2.0 device connected to it will be put on a USB2.0 hub and any USB3.0 device will be put on the USB3.0 hub. When I connect my iPad directly into the iMac it will be put on the USB3.0 hub which is a bit odd since this is a USB2.0 device (the Lightning cable is USB2.0, it doesn't do USB3.0 unfortunately). When I connect it to the external USB3.0 dock/hub it will be put on the USB2.0 hub and function without any issues. Connecting a USB3.0 device to that same dock/hub whilst the iPad is connected to it will result in that USB3.0 device being connected to a USB3.0 hub. You can see this by opening System Profiler and going to "USB" in the list.

So yes there seems to be a problem with the USB ports of the iMac but it isn't power. Unfortunately it seems to be the known issue of USB2.0 devices on a USB3.0 port which is not something that seems to be fixable. The only option is to use a USB2.0 extension cable, USB2.0 hub or a USB3.0 hub that doesn't have this issue. You could bring in your iMac and see if Apple can fix it but I highly doubt it.

Thank you all so much for your many helpful responses!

I placed a USB 2.0 hub in my iMac 5K, but my iMac won't recognize any device :( It's a trust USB 2.0 hub with 4 ports but non of them work on my iMac

The problem still exist, i tried it al.. the SMC reset, reset permissions, disc permissions, delete the ipads and begin from scratch, but non outcome.

My system logs show this after the connect/disconnect happens:

I'm having this problem aswell.
But it happened yesterday for the first time.....

The only thing I've changed is the new version of El capitan public beta.

Before that, everything was normal

Thank you all so much for your many helpful responses!

I placed a USB 2.0 hub in my iMac 5K, but my iMac won't recognize any device :( It's a trust USB 2.0 hub with 4 ports but non of them work on my iMac

The problem still exist, i tried it al.. the SMC reset, reset permissions, disc permissions, delete the ipads and begin from scratch, but non outcome.

My system logs show this after the connect/disconnect happens:

Just curious...Have you taken it in for service yet? You clearly have something wrong with the machine.

No, because i read so much about this problem on other topics like this one https://discussions.apple.com/thread/5523411?start=0&tstart=0

So i think it may not be the iMac itself if so many people have the same problem?

Anyone who can '' read'' my system log and have something to say about it? I have no experience with ''reading'' it.

I have the 5k retina iMac with the i7 4ghz cup and 4gb graphics but I have no issues with usb and connection to my iPad Air 2 even when my iPhone 6 Plus is also connected. The only other USB devices I use are a standard mouse and an Xbox game pad.

I am on the GM of El Capitan.

If I were you I would back everything up and reinstall Yosemite, if the issue persists then go to Apple.

Thanks for your input Marshal! I think i wait for El Captain and if the issue still persist i take it in for warranty.

The weird thing is that my iphones connect normally, also my external HDD's work perfectly fine. It's pure the iPads.

Tried to connect the iPad again and again the problem occurred. Got this in my system log:

Have you tried it with a different USB hub? Trust isn't a brand known for quality products.

The unpowered thing might affect things but in case of troubleshooting it is usually a good idea to try it with another hub. It's to make sure the hub itself isn't causing the issues.

Hey!

No i didn't try another. This was an unpowered hub, does that matters?

It does matter. An unpowered hub is only intended to be used with devices that are powered separately from the computer. Devices relying on power through the USB port should be operated on a powered hub.

Thanks a lot! Then i will try a powered hub if i can find one.

But i find it so strange that only a few iMac 5K owners have this problem, it isn't normal that it connects/disconnects every second, the device should work properly and also without the need of an external usb hub :(

These 4 youtube clips are what i'm experiencing each time






Sorry for my bad English ☺️

This sucks big time.. i thought maybe OSX el capitan will be the answer to all of this, but just updated and the problem still exists.. now i think it looks more like an hardware default then a software default :(

I have similar problems with my iPhone disconnecting every time I need to do a backup and some USB peripherals, like a Keyboard and Mouse stop working suddenly a few times a day.
The problem is the USB on the iMac 5K doesn't have enough power to run multiple devices. I had to buy a separate Thunderbolt dock to keep all the devices running without problems...
I haven't had problems since. Basically all USB devices are directly connected to the TB Dock and I am not using any USB ports from the iMac 5K... Unfortunately the dock is $200 but it might solve your problems... www.macsales.com
