I have just come across more or less the same problem, and have tracked = down the answer. It seems to be a problem with the default PAM set-up on redhat. When you start a console, you can use PAM to control access to system resources (such as a flash card, or scanner, etc) for the duration of = the session, and on finishing the session have the permissions revert to = sane defaults. The file which configures how this is done is in /etc/security/console.perms. You should look for a line which says = something like=20 <console> 0600 <scanner> 0600 root This says that if a user logged on to a console tries to access a file = in the scanner class, the permissions on the file will be set to 0600, = with his ownership, and when he's finished they'll revert to 0600 and root = ownership (at least, I think that's what it means, I don't understand it too = well). If you remove this line, restart pam, and change the permissions on = /dev/sg0 to what you want, they should stick. Cheers, Dave. -- David Neary Phenix Engineering 110 ave Jean Jaures, 69007 Lyon=20
