Currently running 2.6.19-1.2895.fc6 , recently upgraded to fc6 and printing was broken. Updated my gutenprint drives and now printing is great but I can't get scanning to work.

[sephiro499@asus ~]$ 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=0x04b8 [EPSON], product=0x0818 [USB MFP]) at libusb:001:005
# 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

[sephiro499@asus ~]$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

It appears it find my scanner but I can't scan with it, nor does the GUI interface, xsane, even recognize the scanner. Printing works fine though. BTW I could never get the scanner portion working, even when running fc5.

[sephiro499@asus ~]$ dmesg | grep printer
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 4 if 1 alt 0 proto 2 vid 0x04B8 pid 0x0818
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 5 if 1 alt 0 proto 2 vid 0x04B8 pid 0x0818

Try editing the /etc/sane.d/epson.conf file and add a line entry like to the end of the file;

usb 0x4b8 0x118

No dice man any other suggestions?

Sorry, no.......

You can always email the developer: http://freshmeat.net/projects/sane/

This might help you in your quest for a solution. I had a similar problem.

I now have a working Epson Perfection V100 Photo in FC6.

First post was close to the answer.

Go here: http://www.avasys.jp/english/linux_e/dl_scan.html
Choose your setup. I chose my scanner then distro Fedora Core (Other). Get the two RPMs for the iscan and plugin (as of writing v2.3 others could be better.) Lie and say you use Mandrake/Mandriva to get your hands on the 2.5 drivers. Not needed in my case. Plugin component is also unavailable. I didn't ask version questions after it worked with 2.3.

sudo rpm -i those rpm files (or just run everything after su -)

Run this:
sane-find-scanner

You'll get output like this:
found USB scanner (vendor=0x04b8 [EPSON], product=0x012d [EPSON Scanner]) at libusb:003:003

Like the guy before said, replace the "usb" line in your /etc/sane.d/epson.conf with "usb 0x04b8 0x012d" Replace the hex values with the results from your sane-find-scanner (vendor= product=).

*************VERY IMPORTANT***************
I didn't realize this until I had ran into a wall about 300 times. DISABLE SELINUX. There is probably a Fedora/SELinux ninja way out of disabling SELinux but I don't know it and after running headlong into it for an hour I didn't feel inclined to learn.

Disable selinux by running system-config-securitylevel
******************************************

How do you know if SELinux is bending you over?
Run dmesg after trying to run xsane, you'll get denial messages galore. XSane will popup some generic mess about invalid arguments all day. It's meaningless, dmesg tells no lies, SELinux is at fault.

IF YOU HAVE DISABLED SELinux REBOOT FOR IT TO TAKE EFFECT

I'm still working on scanning as a normal user. Currently I can scan just fine by using "sudo xsane" It's not secure, its a pain in the butt, but it works for now.

I'd like to say at this point that I installed FC6 after running XPSP2 for a while for many of the same reasons you left the XP flock probably. To install the very same scanner in XP I inserted the CD and clicked Next a bunch. WAY EASIER. I understand there is a pissing contest over proprietary/open code etc etc ad nauseum...but c'mon...I mean c'mon. What I just had to do in order to scan a W-2 was freaking rediculous.

Jeez, I need a beer after all this "Plug and Play" scanner installation.
