ITunes unresponsive when iPhone connected

Question

When I plug my iPhone 5c to my Macbook Pro via USB, the iPhone device icon shows on iTunes but it just hangs (spinning wheel). I am running the latest OS Yosemite and iTunes and the latest updates on my iPhone.
I have gone through every step in the iTunes: May become unresponsive when connecting iPhone, iPad, or iPod touch - Apple Support article including:
Creating a new iTunes account on my primary User Account (still have same problem) and;
Creating a new User Account on my computer and connecting my iPhone to my current iTunes account (my device is recognized, don't have a problem).
Obviously the problem has something to do with my primary User Account on my computer.  I'm really not sure where to go from here.  Any advice?  Thanks.

Answer 1

I launched iTunes and connected my iPhone before copying/posting the log.  Thank you for your help.
