what gives a clear scan with Linux?

[Michael Havens]

I found the problem. It seems to be a permissions error!

man sane-usb
This is a short HOWTO-like section. For the full details, read the fol‐
       lowing  sections.  The  goal  of  this  section  is  to get the
scanner
       detected by sane-find-scanner(1).

       Run sane-find-scanner. If it lists your scanner with the correct
vendor
       and  product  ids, you are done. See section SANE ISSUES for details
on
       how to go on.

       sane-find-scanner doesn't list your scanner? Does it work as  root?
If
       yes, there is a permission issue. See the LIBUSB section for details.

       Nothing  is found even as root? Check that your kernel supports USB
and
       that libusb is installed (see section LIBUSB).

<edit>
LIBUSB
       SANE  can  only  use libusb 0.1.6 or newer. It needs to be installed
at
       build-time. Modern Linux distributions and other operating systems
come
       with libusb.

       Libusb  can  only access your scanner if it's not claimed by the
kernel
       scanner driver. If you want to use libusb,  unload  the  kernel
 driver
       (e.g. rmmod scanner under Linux) or disable the driver when
compiling a
       new kernel. For Linux, your kernel needs support for the USB
filesystem
       (usbfs). For kernels older than 2.4.19, replace "usbfs" with
"usbdevfs"
       because the name has changed. This filesystem must be  mounted.
That's
       done  automatically  at  boot  time, if /etc/fstab contains a line
like
       this:

              none /proc/bus/usb usbfs defaults  0  0

       The permissions for the device files used by libusb  must  be
 adjusted
       for  user  access. Otherwise only root can use SANE devices. For
Linux,
       the devices are located in /proc/bus/usb/ or in  /dev/bus/usb,  if
 you
       use  udev.  There  are directories named e.g. "001" (the bus name)
con‐
       taining files "001", "002" etc. (the device files).  The  right
 device
       files can be found out by running scanimage -L as root. Setting
permis‐
       sions with "chmod" is not permanent, however. They will be reset
 after
       reboot or replugging the scanner.

Okay, do I need to make it look like:

                none /proc/bus/usb usbfs defaults  6   6

or what do I need to do?
