I have the A7N8X Deluxe mobo and running WinXP w/SP1. When I look under Control Panel/System/Device Manager/Universal Serial Bus Controllers, I do not see that any of my installed USB controllers are 2.0. I did look at the USB driver versions and they seem to be the latest that came with SP1. I just tried to use a USB 2.0 device (IBM Microdrive) and I wasn't really impressed by the transfer speed. I did confirm that I have USB1.1/2.0 enabled in my BIOS. I'm concerned that my system uses only USB 1.1 but not USB 2.0. How can I check it? Thanks.
