Under the properties of the USB Root Hub->Power Management, the “Allow the computer to turn off this device to save power” box is checked. Are you saying to uncheck this?

I have already checked for conflicts, and there are not any. I have taken all the usb devices out, except for the one usb 2.0 device that I own (rio karma), and it still locks the computer. It is using the newest usb 2.0 driver (Intel® 82801DB/DBM USB 2.0 Enhanced Host Controller - 24 CD). As long as this driver is manually disabled, all the usb devices work (at 1.1 speed). If it is re-enabled, all the usb 1.1 devices work, but the usb 2.0 device locks the computer...

I am having the exact same problems with my 8iexp Gigabyte motherboard. As long as the USB2 Enhanced drivers are not explicitly turned off, any USB2 device will lock the system. I have gone so far as to rebuild my machine and flash the motherboard to the newest bios (I believe it is 9F). The only thing that works is if I manually shut off the usb2 driver (thereby enabling everything to run under USB1.1). Obviously this solution is not to by chagrin. If anyone has any work arounds I would be most appreciative.
