Hi,

  I am setting up an Epson Perfection 1260/Photo scanner thru USB (uses =
the Plustek driver).  I have upgraded my Red Hat 8.0's SANE backend =
drivers to version 1.0.13.
  And now, I can see the scanner using both 'scanimage -L' and =
'sane-find-scanner', as root only (I can also use 'xsane' as root only). =
 If I am not root, 'scanimage -L' finds nothing, and =
'sane-find-scanners' finds a scanner on the USB but doesn't identify it. =
 The man page said something about not having the permissions of the =
device file set right if this happens.
  The thing is that when it is displayed, it only shows 'libusb:001:004' =
as the device name, not something in '/dev' (such as the =
'/dev/usbscanner0' or '/dev/sg0' as mentioned in the man page).  So how =
or where do I go to change the permissions???  Out of frustration, I did =
a 'chmod -R 777 /dev' but it didn't help...

  Here are my outputs of the 2 commands by root:

[root@tepeyac root]# scanimage -L                                        =

      =20
