Interesting question, and I cannot tell anything useful about it. On the other hand, I have an Edirol UM-1S, and I currently plan to buy a second USB audio soundcard. Are here some people using two USB devices at the same time successfully, or should I better buy a device which offers both audio and usb in one device? May also be useful for Rick to know if and if so what distros are able to support such a configuration. Best regards ce
