Hello nbardach, Let's make sure you can make full use of the USB and get your data transfered! Have you tried installing the latest drivers for the Galaxy S III at http://www.samsung.com/us/support/owners/product/SCH-I535MBBVZW. Click "All Downloads" and then at the bottom of the page click "Software" and download the .EXE file. Please let me know if this helps keep you connected.
