Reconnect the Device to Your Windows 10/11 PC
When you face a connection error, the first thing to do is to unplug and replug your device into your PC. This ensures your connection isn’t loose and the device is properly connected.
Try that and see if it works. If your error persists even after reconnecting, read on to find more fixes.
Restart Your Windows PC
Your Windows PC’s minor glitches may be causing the “A device attached to the system is not functioning” error. In this case, turn your PC off and then back on to resolve those problems.

- Unplug your device from your PC.
- Open the Start menu and select the Power icon.
- Choose Restart in the Power menu.
- Connect your device to your PC when the PC turns on.
Use a Different USB Port
The USB port you use for the connection may be faulty, causing Windows not to recognize your device. This usually happens when the port is physically damaged.

Step 1. Open the Settings app on your iPhone
Step 2. Keep scrolling until you find the “Photos” settings and click.
Step 3. Once you enter the Photos settings, scroll down to the “Transfer to Mac or PC Settings.”
Step 4. Select the option “Keep Originals” and transfer the files now.
Step 5. Check if the issue is resolved or not.

A device attached to the system is not functioning
You have taken superb photos with your iPhone and want to copy them to the PC to view them on a large screen. You connect your iPhone to the PC, but suddenly there is an error message that runs: A device attached to the system is not functioning.
What does this message: “A device connected to the system is not functioning“ mean when the talk is about iPhone or iPad? There is a communication problem between the PC and the connected iOS device, and Windows thinks that the device cannot be accessed (in this case iPhone or iPad). The error can have various causes:
✘ software issues or incompatibility
✘ connection failure
✘ outdated or incompatible driversBut rest assured: it is a very common problem that can be easily fixed. This point-by-point guide will explain what to do if you see this error.
- The first thing to check:iPhone connection
- A device attached to the system is not functioning Windows 10
- 0x80070141 – The device is unreachable
iPhone connection
The first thing to check
In some cases, the error can occur because of a connectivity issue between the USB device (in this case, your iPhone) and the PC.
To prevent this, disconnect your iPhone or iPad from the PC. If there are other USB devices connected to your computer at the same time, unplug them as well. Once it is done, reconnect your iOS device to the PC, preferably using a different USB port and a different cable (see more about ports and cables below).
A device attached to the system is not functioning Windows 10
First things first, let’s take a closer look at the most common causes of this error.
In fact, for a long time (starting from iOS 11 and iPhone 7), the default formats for Apple’s images and videos have been HEIF and HEVC, respectively. If you are interested in what they are, see what Apple has to say about them. These formats offer the same or better quality than JPEG and H.264 while taking up to 50% less space. On the other hand, they are still much less widespread outside the Apple universe and are not compatible with Windows without any codecs.
So, when you copy your HEIF or HEVC files to a PC, they are automatically converted to JPEG and H.264 formats. However, it is during this real-time conversion the notorious error A device attached to the system does not work correctly can occur.
Numerous tests on iOS devices have demonstrated that the error often occurs when there is no free space on the iPhone or iPad. Why? Well, if there is not enough memory then there is not enough space to save converted files on the iOS device before transferring them to the PC. Suddenly, the system does not understand what is happening, as a result, triggering an error.
Now, how to overcome that?
Solution 1. Free up space on iPhone
We already know that one of the most common causes of the error is the lack of space on the iOS device when converting HEIF / HEVC photos and videos.
This is why we strongly recommend that, before going on to the other solutions presented below, you check the storage space on your device by going to Settings > General > iPhone Storage.
�� It is strongly recommended that you have at least 1 GB of free space available on the iPhone or iPad. If you find that your available space is below this limit, consider freeing up some space on your device. To help you do this, we wrote a guide on how to optimize iPhone storage. Alternatively, refer to an article from Apple with tips on how to check and manage space on your iPhone
Solution 2. Transfer the original files
As explained above, the error occurs when HEIF (HEVC) files are converted to JPEG (H.264) format during the transfer to the PC. It is, therefore, not surprising that we can get around this problem by simply avoiding converting files during the transfer. To do the trick:
- On your iOS device, go to Settings and scroll down to Photos.
- In the section Transfer to Mac or PC at the bottom of the screen, choose Keep Originals.
That did it! From now on, photos and videos will be transferred to the PC with their original extension.
However, as we already know, Windows does not support HEIF / HEVC files. So how do you view them on the PC? Well, there are two solutions:
- Download a codec that “teaches” Windows to read HEIF and HEVC files without converting them to JPEG. These codecs can be paid (like the ones Windows offers when you click on a HEIC file) or free solutions like CopyTrans HEIC.
- Convert the files using a third-party converter. As the conversion will take place on a PC, you can be sure that the error will no longer occur. Here too, you can opt for CopyTrans HEIC, which allows you to not only view HEIF files, but also to convert them to JPEG. Check out the user guide on CopyTrans HEIC for more information.
What makes your experience with CopyTrans HEIC so enjoyable:
✓ Free for personal use;
✓ Allows you to view HEIC photos on PC without converting them;
✓ Converts offline;
✓ Preserves original EXIF data.Solution 3. Transfer photos from iPhone to PC via CopyTrans Photo
By far, the easiest and fastest way is to use our CopyTrans Photo application which has been designed for transferring photos from iPhone to PC.
What advantages does it offer? Well, if the default settings of your iPhone have not been changed, this software retrieves the original HEIC files and converts them using PC resources, thus sparing your iPhone the effort.* As the iOS device doesn’t have to reserve space for conversion, this effectively eliminates the majority of scenarios that can trigger the error. In addition, the protocols used by CopyTrans Photo ensure a very stable connection. And if you don’t want to convert the files to JPEG, CopyTrans Photo can transfer them in their original format.

You have tried everything, yet still the issue persists? Aside from the lack of space during conversion, the error can be caused by various technical problems, such as bad connection, incompatible drivers, or a faulty USB port. See our troubleshooting tips below:
- Solution 4. Try another USB port or another USB cable
- Solution 5. Update Apple Drivers
- Solution 6. Reset location and privacy
Solution 4. Try a different USB port or lightning cable
Good advice not to be overlooked
To avoid any troubles with connection, it is recommended to purchase the original, Mfi certified lightning cables. Using non-certified cables can cause technical problems.
You can tell that the cable is MFi-certified if it has the following logo on the packaging:
If you would like to know more about MFi-certified accessories, be sure to read the guide by iGeeksBlog.
Also, remember to check for damage. Even if the cable seems to be all right with no visible defects, it may still be wise to try another one.
You can also try connecting your lightning cable to another USB port because it is a possibility something went wrong with the first one. If your PC has more than two ports, it may be helpful to check all of them, one by one.
Solution 5. Update the Apple drivers
In some cases, a bad connection may be caused by outdated drivers.
- Do you want to install the latest Apple drivers without having to deal with iTunes? We made it possible! To do this, use the CopyTrans Drivers Installer application. Here is the article that explains how to proceed:
*CopyTrans Drivers Installer will ask you to uninstall iTunes: this is a temporary measure, and you will only need to do this once.
