In this article, we are going to take a look at what this error is and what causes it. We will also give you a list of methods you can try to solve this issue. Let’s get started.
“A Device Attached To The System Is Not Functioning” Error
The need for more storage space on mobile devices has increased drastically over the last few years. 64 GB of storage (the minimum on an iPhone) can seem small especially if you shoot a lot of 4K 60FPS videos. Cloud storage is an option but storing your media files on a computer is the most convenient way of increasing the available space on your iOS device without losing data. However, if you’ve tried to move your media files from an iPhone or an iPad to your Windows computer, you can run into the “A device attached to the system is not functioning” error message and it can be pretty annoying.
This error is mostly seen on Windows PCs and not on any of the MacBooks. It usually pops up when you try to move high-resolution media files from your iPhone to your PC and it will not let the transfer happen. Moreover, it will disconnect the iPhone and you will have to reconnect it manually again. Fortunately, the fix for this error is as simple as changing a few settings on your iOS device and it will be discussed in the next section.
How to Fix this Error Easily?
We have a list of methods you can use. The first method will work in 99% of cases and we recommend you follow the order of this list. Even if it doesn’t we have other methods that can help you out. Let’s jump right into it.
Method 1: Changing The iPhone Settings
This is the best and the easiest way of making the “A device attached to the system is not functioning” error message go away. It should work for most of the users reading this article. Just follow these simple steps.
- Make sure that your iPhone/iPad isn’t connected to your PC.
- Open up the Settings app on your iOS device.
- Scroll down and tap on Photos.
- Next, scroll down and find the TRANSFER TO MAC OR PC header.
- Check the “Keep Originals” options.
These steps should take care of the error on your PC. However, you can run into a different issue here. If you use high-efficiency codecs like HEIC, your copied thumbnails can look weird and the picture quality would not be that great until you convert them to .jpg files. This can be hard especially if you have hundreds of pictures. Fortunately, there’s an easy fix for this too.
- Open up the Settings app.
- Scroll down and hit the Camera.
- Select the Formats option.
- Under CAMERA CAPTURE, check “Most Compatible” and all of your future images will work fine with your computer.
Method 2: Check the USB Port and Cables
If method 1 hasn’t worked out for you then don’t worry, you still have options. A faulty or outdated USB port can sometimes cause this error to show up. We recommend you try connecting your device to other ports and see if that works. You can also try connecting your device to a USB 3.0 port (this has worked for some users).
A faulty lightning cable can also cause problems while transferring files. You can test your cable by connecting it to another iOS device or by using another cable. Also, make sure that your cable is certified. Apple devices refuse to work with uncertified lightning cables.
Method 3: Check Your Drivers
Drivers don’t automatically get updated and can cause issues in your PC. Outdated drivers for your iPhone can cause error messages to pop up from time to time and it is important to keep them updated. You can go to the device manager and update it from there. It’s honestly a bit of a hassle and that’s why we recommend that you use Tweakbit driver updater. It will update all of the outdated drivers on your PC and make sure it runs properly. Using Tweakbit is pretty simple and it even offers a rollback option (just in case the updated have their own issues).
You can download the free version of the tool and quickly update all of your drivers. You can also check out their website to see if you’d be interested in buying the full version.
