I wish I had an answer for you, but because I didn't have that problem, I have no idea of what you should try now.
One thing that I forgot to mention was that my notebook does have XP MCE2005 on it, and I have read elsewhere that the pro audio community has had problems getting that version to work with various sound cards/drivers.......but, just like my desktop, I've had zero issues with 0404 USB vs. onboard sound conflicts.
