Can you send your "lsusb -v" output? Attached. As far as I understand it, there are two endpoints for audio and two for MIDI. The MIDI part seems to be initalized fine although I don't have any MIDI device to test it. And in the log from windows machine the audio part does some intialization and then only buch of isochronous transfers. -- Cyril Hrubis --AqsLC8rIMeq19msA Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="lsusb.txt" Bus 001 Device 005: ID 0644:8021 TEAC Corp.
