I think I'm going to label "friendly" standard usb sound devices which work "as is" without requiring an entry in usbquirks.h (which does not mean the opposite will mean automatically "unfriendly" ) Thanks for these informations and also for people who replied to me off-list. --=20 Emmanuel Kasper System Administrator www.libera.cc Find, compare, buy Linux & FreeBSD compatible hardware --------------enig23961FE5411A3A4F832425A0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIUNM4wfhkdwZoef4RAsMFAJsG5kGawA4WMqnBtQy1o5hzWjE3DACfX6WC OSryl6rljaQK6aBzmyOcJes= =13gU -----END PGP SIGNATURE----- --------------enig23961FE5411A3A4F832425A0-- --===============0604372363709068494== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel --===============0604372363709068494==--
