Fedora 13, xsane unable to find MFC-495CW scanner.
Let me begin this by telling you that is it working fine from my Ubuntu 9.10 netbook. I would like to also have access to the scanner from my Fedora 13 laptop.

I have installed brsane3:

[davdunc@mps1530 ~]$ rpm -qa | grep brsca

I have identified the scanner using brsaneconfig3:

[davdunc@mps1530 ~]$ sudo cat /usr/local/Brother/sane/brsanenetdevice3.cfg
DEVICE=SCANNER , "MFC-495CW" , 0x4f9:0x22a , IP-ADDRESS=

The scanner appears to be active:

[davdunc@mps1530 ~]$ brscan-skey -l

 SCANNER          : brother3:net1;dev0  :        Active
[davdunc@mps1530 ~]$

But if I attempt to locate it with the command sane-find-scanner I get the following:

[davdunc@mps1530 ~]$ sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x0483 [STMicroelectronics], product=0x2016 [Biometric Coprocessor]) at libusb:003:002
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.
[davdunc@mps1530 ~]$

Needless to say, the scanner is not located and xsane attempts to scan from my biometric scanner.

Other possible concerns:

in fedora i would access the scanner from Gimp

dose Gimp "see" it ? if so dose it scan ?

Thanks for the reply John. Unfortunately, Gimp uses the sane plugins, just as xsane does. So your suggestion actually points me back to the same tool that I am having problems with just with a different skin.

Gnome-scan I thought might be able to find it, and that is a different tool, but it doesn't.
I am thinking that there is something about the device that makes it appear for the tools from Brother, but prevents the creation of a device or something. There is a disconnect between the discovery of the device by brscan and the delivery of that information to the other tools as a device.

By the way, SELinux is disabled for all tests so far.
