How about just disabling USB legacy support in the bios completly? Unless you have a USB keyboard that you need for a bootloader screen or BIOS configuration, that's the recommended setting (due to all of the horrible BIOS USB bugs we have seen over the years.) If after you find a USB 2.0 device, and have any problems with it, please let us know. thanks, greg k-h ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
