In order to test libptp, it looks like I need libusb. There is a Ubuntu package for libusb.
craig@linux-silver:~$ sudo apt-get install libusb-1.0-0-dev

Install went fine.
I next downloaded libptp source code from Sourceforge.
craig@linux-silver:$ tar xvf libptp2-1.2.0.tar.gz
Extract went fine.
I got this error when I tried ./configure
./configure: line 13153: test: : integer expression expected
configure: error:
*** You need the 0 line of libusb which is at least 0.1.8.
*** Higher versions might not be compatible! Download and istall
*** libusb version 0.X.X from http://sourceforge.net/projects/libusb/ or
*** use --disable-ptpcam option to build without ptpcam tool.
The easiest thing is to install libusb 0.1.8 and see if it compiles. I compiled and installed libusb 0.1.8.
I then compiled libptp2-1.2.0
It installed in /usr/local/bin
craig@linux-silver:/usr/local/bin$ ls -l ptpcam
-rwxr-xr-x 1 root root 159904 Jun 29 16:32 ptpcam
When I first tried to run ptpcam, I got this error:
craig@linux-silver:~$ ptpcam
ptpcam: error while loading shared libraries: libptp2.so.1: cannot open shared object file: No such file or directory
I added /usr/local/lib to my LD_LIBRARY_PATH
craig@linux-silver:$ export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
craig@linux-silver:$ ptpcam
USAGE: ptpcam [OPTION]
Seems to be working. I’m going to plug in the camera.

I used pydoc gphoto2 to access the docs.
I saved this code snippet into a file called, theta-usb.py
from gphoto2 import *
theta = camera()
theta.init()
folderList = theta.list_folders_in_folder('/')
# print(folderList[0]) #core dump
print(theta.summary)
print(theta.abilities)
theta.capture_image()
The program works over USB, including the ability to take a picture
