I just switched from iPhone to this S3 on AT&T. I am on a desktop running Windows 7, and I have a USB WiFi adapter as well as a USB wireless mouse. When I plug my S3 into the computer, the internet and the mouse stop working. (The computer DOES recognize the phone, ironically.) At first I thought it was that awful Kies program that I naively installed, but it happens even when Kies is not installed. What should I do? It's driving me nuts so I would really appreciate any help...
