Hmm, that sounds strange. How long is a noticable lag? :) Have you tried with ecasound? I've personally tried a few USB audio devices and didn't experience any unusual latency problems. Something like "ecasound -b:256 -z:nointbuf -i alsa -o alsa" should be enough for effect-box type real-time processing. Maybe I should test that again... PS Although I must say, due to old USB-related work projects, I have a real love-hate relationship with USB. Nowadays whenever I see someone (un)plugging a USB-device, I automatically expect the machine to halt completely or plain just not work. :) Fortunately there are exceptions, my Rio500 and Midisport2x2 have almost changed my mind.. they actually do work. :) But, but... don't take these words too seriously. -- http://www.eca.cx Audio software for Linux!
