I am using an Edirol UA-1X with the standard Demudi-kernel (version 2.4.22 with ALSA 0.9.8). While I also see the "default" id I do not have the problems which you describe. I have also successfully used the UA-1X with SuSE 8.2.
I have not yet really tried to use it with a 2.6 kernel and a newer version of ALSA.
