It will not detect my HP ScanJet 8200 flatbed scanner. But scanimage -L gives:
Code:
device 'avision':libusb:001:005' is a Hewlett-Packard ScanJet 8200 flatbed scanner

I followed all the steps in the wiki and cannot seem to find out why it won't connect.

Have you tried running xsane from the command line, to see if it gives some informative output?
Also, have you tried to run xsane as root? Of course I'm not suggesting to always scan as root, but if xsane works when being run with full privileges, you've probably got a permission issue that can be resolved by writing a suitable UDEV rule. For instance you could create a group for all users allowed to use scanners, add your user to it, and write an UDEV rule that gives this group access to the scanner.

Another crazy idea: Have you tried to use other USB ports, or a different cable? I had similar issues (scanimage found the scanner, but xsane couldn't use it), and I'm meanwhile certain they were caused by a cheap USB cable... What confirmed that it's the cable was that after switching it with the printer cable of my girlfriend's computer, her printer didn't work any more... Funny enough, I'm still using that cable, but on a different USB port, where obviously my mainboard has slightly higher voltage levels (or accepts lower voltage input).

I will try running it from the command line. I'm not sure, but I thought that I had. I did try running it as root, but it gave the same error.

I like your idea of a different USB cable, because I have two cables piggybacked since the original one is not long enough. So I will try that and post back.

Thanks.

Well, that didn't work. I used a completely new USB cable, plenty long enough, but it was of no help. I get the error:
Code:
Failed to open device 'avision:libusb:001:0018':Operation not supported.

And this is running xsane from the command line as root. which, of course, first gives me the message as to how dangerous this is.

Nor does it matter which USB port I try.

wondering if you have either SANE_BACKENDS="hp" or SANE_BACKENDS="avision"

just a shot in the dark

Good question. I didn't really know there was a difference, to tell the truth. How do I change that?

Oh, I didn't even think about SANE_BACKENDS...
It's an auto-expand variable for portage (similar to the LINGUAS or the VIDEO_CARDS variable) and can be defined in /etc/portage/make.conf

I added the SANE_BACKENDS="hp" to make.conf, but it made no difference.

I have also been unable to get xsane and hp to work properly. However, I did find a workaround that is very effective. That is to use hp-scan. Here is the man page if you want to try it

Thanks Doctor, but the link you provided didn't quite show me what to do for a scanner. It says the Hplip does not work for scanners. And, unfortunately it seems that my scanner is not supported by SANE Backends, either. When I run "sane-find-scanner", I get:
Code:
found USB scanner (vendor=0x03f0 [hp], product=0x0b01 [hp scanjet 8200]) at libusb:008:002

And then trying scanimage -L after editing and commenting out "avision" in /etc/sane.d/dll.conf, I get No scanners were identified. Don't know why it was identifying it as avision before, but now it looks like I'll have to replace this HP ScanJet 8200 with one that IS in the SANE Backends list.

Unless someone more knowledgeable than myself has any other suggestions.

It shows your scanner is supported.

My scanner, a HP Scanjet 7400c, requires the avision backend, the same might be true for yours.

Yes, that is true. I found that while doing some digging.

I also discovered that the avision backend is for my scanner, so I went back and uncommented that in my /etc/sane.d/dll.conf and restored my make.conf also. I went through the Gentoo Wiki as well, which btw is a bit outdated since hotplug and coldplug are way out of date. So far nothing is helping it to connect. I can detect it with both sane-find-scanner and scanimage -L as well, but something is still not making the connection. It keeps coming back with Operation not supported, which is not making sense. Yet.

I going to try a reboot.

The reboot did nothing to help. Also ran through the Hplip setup with the tarball and after following the instructions to download it to my desktop, now I have a crap load of files all over my desktop. If it's not going to work, I want to clean up this thing. I tried to run the hp-setup and hp-scan and I don't guess I know where to find these commands, because that is what it says, "Command not found". If the instructions are going to tell one what to run, why do they not also tell one just where to find the command? This sort of documentation is no doubt the reason so many inexperienced users (of which I am one) experience great frustration.

I had absolutely no trouble whatsoever installing Cups and my Oki 6100C printer.

Strange...
I'm honestly out of clever ideas, and back to wild guesses... Have you enabled the global "scanner" use flag?

Can you post your configfile (/etc/sane.d/avision.conf) and the full output of "lsusb" please. Maybe you need some tweaking there.

Thx, bb

EDIT: Please add "avision" back to your make.conf and dll.conf. It is needed for your scanner according to the sane website!

First my make.conf:
Code:

#SYNC="rsync://rsync3.us.gentoo.org/gentoo-portage"

Now my /etc/sane.d/avision.conf:

And my complete /etc/sane.d/dll.conf file:
Code:

Oh yes, the output of lsusb:

Ok it looks like this could be wrong, because you have enabled the usb-useflag globally in your make.conf. This is because of the RDEPEND in sane-backends:
Code:

usb? ( >=virtual/libusb-1-r1:1[${MULTILIB_USEDEP}] )

I think it should look like this according to your current USB connection:
Code:

# These are the possible options. Normally any scanner
# should work just fine without them - and they are only
# needed for test and debugging. So if you experience problems
# and you solve them with enabling options here, please notify
# the SANE/Avision maintainer: Mike Kelly <mike@piratehaven.org>

#scsi AVISION

#scsi MINOLTA
#scsi MITSBISH MCA-S600C
#scsi MITSBISH MCA-SS600
#scsi HP
#scsi hp

#scsi /dev/scanner
# usb libusb:002:003
# usb 0x03f0 0x0701

usb libusb:008:002


Please try this and check whether you can run scanimage as root from the console. We should have a look at xsane later, since you are not able to scan at the moment at all.

scanimage -L (as root in console) produces the following:

mark2,

Are you in the scanner and or plugdev groups?
One of those is obsolete but I can't recall which.

I am in the scanner group, but not the plugdev group. Also the usb group.

mark2,

I think the scanner group gave access to /dev/scanner in the days when the kernel had a usbscanner option in menuconfig.

When libusb came along /dev/scanner went away.
If you have plugdev group on your system, add yourself to it, then logout and back in to pick up the new group membership.
If the plugdev group does not exist, you don't need it.

Google suggests my memory is faulty and plugdev came along with HAL, which has long since gone away again.

I used getent group to show:

So, it does not appear the plugdev exists. And I would assume since my kernel is version 4.0.5 that usbscanner is not an option.

If you are still getting the "Operation not supported", I think it is probably some configuration, library, or driver issue as opposed to a permissions issue.

Maybe try running with 'strace' to see how/when the error code is generated.

The only problem I ran into with strace is that there is so much more code than I can capture on a screen. And it won't wgetpaste because it says there is nothing to post.
