Jochen,
|
|
<BR>
|
|
<P>the only way you can get it to work is by making the programs that
|
|
<BR>
|
|
access the pio device (the frontends) SUID root:
|
|
<BR>
|
|
<P>chown root xscanimage xsane scanimage
|
|
<BR>
|
|
chmod 4755 xscanimage xsane scanimage
|
|
<BR>
|
|
<P>... of course you have to provide the correct paths for the
|
|
<BR>
|
|
three programs.
|
|
