Apologies for the unclarity, it's USB.

On the Pi a file manager window can be opened, with a URL of
gphoto2://[usb:001,008]/
and a single folder named store_00010001

If I double-click on the folder an error dialog saying
"Failed to get folder list: -1 Unspecified error"
with an "ok" button pops up.

A private email pointed me to
https://itunes.apple.com/us/app/documents-by-readdle/id364901807
but that seems unidirection _to_ the iPad. My immediate interest
was moving content _from_ the iPad.

If I look at /dev on the Pi I see /dev/sda but no /dev/sda1. The little
"eject" button at top-right on the screen reports "no ejectable devices"
but it does the same thing on my camera and I can extract photos from it.

Nmap reports
Starting Nmap 7.40 ( https://nmap.org ) at 2019-02-01 14:55 PST
Nmap scan report for 192.168.1.18
Host is up (0.0067s latency).
Not shown: 999 closed ports
PORT      STATE SERVICE
62078/tcp open  iphone-sync

Nmap done: 1 IP address (1 host up) scanned in 44.24 seconds

It appears the iPad is locked down tight.


Thanks for writing!
