[LAU] sound devices usbpre2

Just got one -_- it works out of the box in usb 1.1.. in theory it should also work in usb 2.0.. or that depends, what is the state of usb2-audio on linux? if it's ok this litle thing should work in some way.. It's a real nice piece of hardware, the smell off quality is allover.. the only bad thing is that -15dB PAD's and phantom power is controlled with dip switches wich aren't really accesible by hand.. So, does anybody know the state of usb2 audio on linux? it's supposed to work in usb2 on newer macs without 'external' drivers... And does anybody know how to set the default soundcard by name rather than a number on archlinux. I've tried this; https://wiki.archlinux.org/index.php/ALSA#Random_Lack_of_Sound_on_Startup but I really can't seem to get it working..
