This post is just for information. I wanted to make a backup of my iPad Mini 4 today so I could update the iPadOS. So I connected to my MBPr mid-2015 with a cable and opened Finder (Big Sur also updated, so 11.4). The iPad was fully charged. But when it connected it would not stay connected. Connect/drop, connect/drop, over and over. I was unable to get the backup done because the cycling on/off was so short that I couldn't even click on the iPad name in the sidebar of Finder!
So I disconnected and did an iCloud backup over WiFi. Not the best, but got it done. Then did the update to the iPadOS. Once it was updated, I tried again to connect to the MBP and got exactly the same issue. Thought about it for a couple of minutes and had the bright thought that maybe it was overdrawing the USB port for power, even though it was fully charged. Connected a USB powered hub, connect iPad to hub. The iPad connected to Finder, stayed connected and the backup to the local drive was completed with no issue.
I'm posting this here in case anybody else has the same symptom of connect/drop and wonders what to try. Not expecting any fixes, jus found it curious and I learned something.
