(sorry, i'm a freeBSD-newbie ;) ) thanks flo --------------enig64F0B7CF7B9CE9B2E0868F3C Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBAgAGBQJQqp+AAAoJEHPd9QK/nPqlkbMH/0rXXl56OCqLswtxO2o0iUg/ /Pw6covi1+z2K8nugwp5oPic2lC73WmdVd2jT2m57LPlGuBqR7XxAaFKtk16us9Y pqOvinKjKcv8q+GKDk7G8TmEn512Nm8/7e9Wsd3BdMLuvx0w0keqExnEbGCsjtao OUb94RdgOUbI8zS2054/moLhmhiwDix4gf2UEVyWSlyAmcWE6zoCpXTD/fK9X/x4 i2PL6cM4wbIIgsDmzfaS6/gv1NVCHqw3ltTrpSFsinT4jQYatgvAqLam0Cp+EqwI c17bkXedl7eS9X4jCj5G8vfR7OOu3xQtN3FUscpJN+pgKCpenD86/o3pEI4n+ZQ= =ob+r -----END PGP SIGNATURE----- --------------enig64F0B7CF7B9CE9B2E0868F3C-- _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
