The windows driver always sets this 8 bit register [...] to its maximum 255 to avoid problems with some computers." */ maybe the ene bridge doesn't like to have devices connected, with a higher latency timer value, that it is using itself? tim --=20 tim@klingt.org http://tim.klingt.org Every word is like an unnecessary stain on silence and nothingness Samuel Beckett --------------enig8A5AA9A80207727C09DA79D9 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkqBHRsACgkQdL+4qsZfVstQcQCdH5e7wE9ir0El4P2WHehkdSN7 AAIAn0BW67GO+xay4c2xmcXeAx1ZuaCQ =p1ip -----END PGP SIGNATURE----- --------------enig8A5AA9A80207727C09DA79D9-- --===============1486019005925576001== 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 --===============1486019005925576001==--
