Hi I just built my system, it is a biostar g31-m7 te with E6750 and 2 gigs ram. The problem is when I had XP on it the usb was 2.0 and when I replaced XP with 7 now everytime I plug in a USB device it tells me I need USB 2.0. I went to Biostars website and the only USB 2.0 drivers are for XP. I downloaded them and tried them and they wouldn't install on my windows 7 ultimate 64 bit OS. Yes I did use the disk that came with the Motherboard. Has anyone else had the same problem or have any ideas what to try? Thanks.
