I have used a USB 1.1 IF on my netbook running at 800Mhz (half speed) and was still able to run the IF at -p 64 -n 2 (2.67 ms Latency) without xruns. I did have to back the latency off if I ran too many softsynths or too many effects, but even double that is not bad. -p 64 with USB 2 devices seems to be the lowest too. I run into memory problems before CPU use problems in general with only 1G memory :) -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
