While 2 UX8s may not be able to run from the same computer you can definitely run multiple audio interfaces from the same computer as I was running 3 smaller audio interfaces into this same laptop before getting the UX8 and continued using 2 of them with the UX8 until I pickup up the second one.  Given your incorrect supporting statements I'm not sure if you're right about the first one or not, hopefully someone from Line 6 can give me a definitive statement.

When I used Audacity I wasn't using ASIO, Sonar seemed to work with my multiple ASIO devices just fine, and I didn't use ASIO4all.  Regardless this doesn't really have anything to do with my initial question/problem which is not that the two ASIO devices won't record, the two UX8s I have aren't being allowed to even connect to the system at the same time.  If this isn't a problem that can be worked around then the rest of the semantics aren't too helpful.

Thank you, that was, unfortunately, the answer I was looking for.  I know other devices like removable hard drives get around the issue somehow, I was just hoping the UX8 could do something similar.  I need a UX16...
