Tried three combinations of one alsa-midi-latency-test process writing to one Romio II port and another reading from another Romio II port : alsa-midi-latency-test -o 24:0 -i 28:7 & alsa-midi-latency-test -o 28:7 -i 24:0 alsa-midi-latency-test -o 24:0 -i 28:7 & alsa-midi-latency-test -o 28:7 -i 24:1 alsa-midi-latency-test -o 24:1 -i 28:7 & alsa-midi-latency-test -o 28:7 -i 24:1 They all worked without a hitch. Tried the Romio II with itself again : it failed as before. Found a large number of "usb_submit_urb: -22" messages in kern.log for yesterday (but none for today). -- André Majorel http://www.teaser.fr/~amajorel/ _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
