I could also see benefits for other devices like HID where the current ordering is done after a first come - first serve approach where the minor device numbers follow the order the devices appear on the bus which is quite easy to mess up and never consistent; Applying your scheme to and-class devices also would allow to link whatever device to a fixed device node which could solve many problems as far as I can see. Can you elaborate how you retrieve the IDs of a firewire or USB controller? =20 --=20 Servus, Daniel --=-wsdg4Nm9oh3Z9BU1HIIK Content-Type: application/pgp-signature; name=signature.asc Content-Description: Dies ist ein digital signierter Nachrichtenteil -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQA9egBzchlzsq9KoIYRAmq4AJ9g7481XM215vs4CJ8D5MbgCM0QLwCcD6Gc ea1M4f3lOlicf5yfKMoD6wA= =ihle -----END PGP SIGNATURE----- --=-wsdg4Nm9oh3Z9BU1HIIK--
