ipod

Hello, I'm using 10.9.2, latest version of iTunes (which I reinstalled from Apple just to be certain), running on a GA Z87X-D3H board with a GeForce 770 Graphics card. Anytime I go to transfer songs to my iphone, ipod, ipad, iTunes will freeze and nothing actually gets transferred. A week ago...

I have just installed OSX Mavericks (10.9) on a Acer Aspire M3970 (with a few bumps along the way), and everything works fine, except whenever I conncet an iPhone or iPod they do not show up, or even charge. USB's, keyboards and mice all work fine though. iTunes is update to the latest version...
