You will find that the error message “the device has either stopped responding or is disconnected” keeps popping up when you attempt to copy your PC data to any external storage device, such as iPhone, iPad, USB flash drive, etc.

Fixes: The Device has either stopped responding or is disconnected

With the general troubleshooting advice listed below, hope your issue can be solved. Try them one after another to check if your mistake still exists.

1# Check the USB port

The first thing you can do is to check the USB port since it sometimes can be vulnerable. Simply put some different cables or USB in the same port or use the same cable or USB in any other USB port of your computer. This might solve your problem.

2# Check your iPhone settings

Sometimes everything is OK except for your iPhone’s settings. Since iOS 11.4, iPhone/iPad has included a new security feature called USB Restricted Mode, which can block your iPhone from connecting to computers and other devices if they haven’t been unlocked for more than an hour.

It is suggested to disable the feature when you transfer files from PC to iPhone by going to iPhone Settings > Tap Face ID & Passcode > Enter your device passcode to continue > Scroll down to locate and toggle off USB Accessories.

Now, you can re-connect your iPhone to computer to have a check. Please remember to tap Trust on your iPhone when asked, so that your PC can get access to your iPhone.
