I can't sync my ipod Touch
After completing an iTunes update last night, I can no longer sync my iPod Touch (6th Generation). It's as if my computer doesn't read it any longer via USB. I've tried restarting my iPod and my computer. Both have the latest updates. I've tried every USB port and nothing works. I bought music online last night and now I can't even get it onto my iPod to enjoy this weekend! Any advice? Thank you!
iPod touch, iOS 9.3.1
