Same problem, trying fruitlessly to get my USB-Midi cable to communicate between my Korg PA-50 and Sonar, despite Device Manager telling me everything was OK. This on a Toshiba A120 laptop with Intel single-core and XP SP2. Yet it works OK with my L300 laptop running Vista. Now, with Tito Pulpo's simple registry modification, my no-brand Chinese USB-Midi interface works fine on the A120 as well. Many thanks! I can stop tearing my hair out.
