leeperry: Did you see my question earlier? Do you have a list of the driver version changes anywhere? I have bookmarked some list you pasted here earlier but it goes only to 1.48.
Also I haven't yet had time to audition my setup with the new firmware and drivers on U3. I'll let you know when I get chance to do some auditioning. if you're going to compare 1.61 to 1.63, that would be very interesting.
