iPhone a device attached to the system is not functioning

Whenever I try to copy files using file explorer on my Windows computer from my iPhone it fails with the following error:  A device attached to the system is not functioning.

Most of the time it will copy a few files before giving this error and failing to copy any more files.  I Googled this error and tried the 3 most common suggestions to fix this (none worked for me) which were: 
1. Use a different USB port on my computer (same error). 
2. Use a different iPhone cable (same error).
3. Try on a different computer (same error). 

What worked for me allowing all the photos and videos to be copied at one time was the following:

Solution: 
1. On your iPhone go to - Settings - Photos and scroll to the bottom. 
2. Under "TRANSFER TO MAC OR PC" - change from Automatic to Keep Originals. 

3. Reconnect your iPhone to your PC and retry copying your photos. 

Note - you may end up with a few .HEIC files which your Windows computer might not recognize.  If so, you can use a free .HEIC to jpeg converter downloaded from the internet.  My preference is to install a Virtual Machine on my PC and use that to test any freeware software that I use for something like this.
