Here, we’ll be taking a look at five potential troubleshooting steps to try and resolve the “device attached to the system is not functioning” error that you’re getting, when transferring photos to your computer.

Install / Update iTunes

Even if you’re not using iTunes to sync or back up your iPhone or iPad, it’s necessary to still have it installed for avoiding issues while transferring photos and videos.

Check out our article for step-by-step instructions, if you’re confused.

Set Photos to Keep Originals

With the introduction of iOS 11, iPhone and iPads by default use Apple’s HEIF (High Efficiency Image File) format to store photos at a reduced file size. However, while transferring to PC, they are converted to the traditional JPEG format. By skipping the file conversion, you could possibly resolve this issue. Head over to Settings -> Photos -> Keep Originals to make sure your device transfers the original files without checking for compatibility.

Reset Location & Privacy

When you connect your iPhone or iPad to a PC for the first time, you will get a “Trust This Computer” prompt on your device. If you accidentally chose to not trust for whatever reason, it could stop you from transferring photos to your computer. You can reset your location and privacy settings to get this prompt once again when you connect it to your PC. This can be done by going to Settings -> General -> Reset -> Reset Location & Privacy. Then, disconnect and reconnect your device to the computer.

Use a Different USB to Lightning / USB Type-C Cable

Apple’s lightning cables are susceptible to wear and tear over time. Sometimes you might even have trouble charging your device and an “accessory may not be supported” error might show up. This indicates that your cable may indeed be faulty. Therefore, try using a different cable to see if it resolves the issue.

Try a Different USB Port

Disconnect your device from the USB port it’s connected to and try a different port, so that the file transfer isn’t hindered due to a faulty USB connection. This is a fairly simple trick that often resolves these sort of issues.

Update iOS / iPadOS to the Latest Version

Sometimes updating the system software on iPhone or iPad can remedy errors that are expedience with connecting a device to a computer. Backup the device first, then go to Settings > General > Software Update and installing any available updates.

If none of the above methods worked in your favor, try force rebooting your iPhone or iPad. You could even try restoring your device from a previous backup using iTunes or iCloud, though the issue is usually not with the iPhone or iPad.

By now, you should not be seeing any sort of errors while trying to connect the device or transfer photos and videos to your Windows PC. You could also use the same techniques if your iOS device is not being recognized by iTunes.

    iTunes is so bad on Windows itself I can’t remember the last time I had it installed on a Windows PC? I’ve tried the App from Microsoft store and the iTunes software download and neither are very good. Really too bad that their isn’t a better way.
