Are you sure you really get 24 bit duplex? I don't think USB 1.1 has enough bandwidth. I was burned during a show at STEIM by accidentally switching the advanced switch on and the USB bus threw a kernel panic as soon as I hit a song with an [adc~]. Took me a while to figure that one out.

... the UA-25 only has 2 ins and outs at 16bit, you can do 2 in at 24bit or 2 out at 24 bit, but not full duplex.
I think it's slightly more complicated than that!
With my UA-25 I get full duplex at 24bit with the sample rate switch set to 44.1kHz and 48kHz (and the advance mode switch set to 'on', in case that matters). At 96kHz it is probably different, but I never tried that yet. (This is with the original UA-25, which I believe has been discontinued - the later versions may have different behaviour.)
