scorched earth option

go to device manager's view menu if you don't have a show hidden devices option

try this
Remove Old Drivers After Upgrading to New Hardware

if you do have the option enable it then follow the instructions for removing drivers for uninstalled usb devices or installed ones that may be causing issues

you can always reinstall the drivers

then reboot

just a thought did you install the m-audio driver as administrator
