I try to developpe a usb sound driver for a Alesis Multix 8 USB2.0 http://www.alesis.com/multimix8usb20 The output interface is allready fonctional, but the Input not :-( Because there is 2 end point for it. The first one is on Isochronous mode and the other is on Bulk mode I don't know how to declare the second endpoint in the quirks_table. Where can I get a good documentation or help about the alsa USB sound structure. The only informations I have about the devices, are dump from windows thanks -- Salutations __ /----------------\ |~~\______/====\__ | ( Laurent Epinat )---- \LE______======= )-+ \----------------/ ----|/-- | mailto:l.epinat@free.fr (O) http://lepinat.free.fr
