How about this? I ran 'sane-find-scanner' and got the following. Does this indicate anything?
Seems to suggest that there is a "permissions" problem. Not sure what that means.
# 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.

The 'simple-scan' debug output doesn't show any problems, and the 'sane-find-scanner' output is as expected. If there was a permissions issue (with the scanner device node) then xsane would not be able to function with it.
BTW, it simply probes the enumerated usb devices and the other entries are for devices that are NOT scanner devices. The applicable scanner device is
Code:

So, still, by all indications simple-scan should be working just fine! But it isn't. Thanks for your help. Much appreciated. If any other thoughts occur, please let me know.
Hi! I have a new Gigabyte computer with Debian 8 installed and I'm trying to get this work with a Canon Lide 110 scanner. The scanner is being recognized by the computer but the output quality isn't very good. At first the image was corrupted and almost illegible. I put up the resolution to 300 and it was much improved but still not a sharp clean copy. What do you suggest in order to get resolution and shade accurate? I just scan text files and my printer is black and white so color is not an issue. Thank you in advance.
Sounds risky! What's disconcerting is that everything appears to be in order and yet simple-scan won't perform. It's possible that there's something simple and obvious that I'm overlooking when attempting a scan, but I don't think so. It appears you just insert a page into the scanner...and then scan! That's what I've done but the scan refuses to start.

IIRC, Picassa is a image viewer for ms-windows. For a while it was bundled with Wine so it could be used in Linux, but that package is no longer available (from Google?).
The GNU Image Manipulation Program, aka, The Gimp, is used to create and/or edit images. It is not as powerful as Adobe Photoshop, but almost, and enough so that many illustrators and design professionals use The Gimp to make a living.
Scanning in Linux can be difficult, depending on your scanner.
As my HP flatbed scanner is not well supported by Sane, the backend used by XSane, the results have never been satisfactory and I've spent so many hours trying to tweak XSane it could easily add up to days if not weeks. No joke.
As I scan almost daily, I finally installed VirtualBox and into that ms-windows Xp and into that the HP drivers for the scanner. Turns out perfect scans of reasonable size.
When a new version of Sane was released a week or two ago I gave XSane another try and while it was an improvement the results were still not anywhere as good as those done with the ms-windows HP drivers.
VirtualBox can run on your Linux desktop as "just another application," but it will take up memory and resources. That shouldn't be problem with many "modern" computers.
Good luck.
Edit in: Just stumbled across this article. It has nothing to do with scanning, but it does list some excellent Linux based design tools (applications).
Well, I'm not going to be so impolite as to tell you are "wrong," but I have already tried, several times, as new versions are released, your suggested software and it doesn't support my HP flatbed scanner. Sane provides partial support, but not enough to render quality results.

If there isn't an HP driver at www.hp.com for your operating system, then unfortunately VueScan won't work with this scanner. VueScan uses a plugin library that's installed with the HP drivers to talk to this scanner, and doesn't work with this scanner without this plugin library.

Let me try... I installed a new devuan fresh system. I got the vuescan and try to run it on the lide 120....
EDIT: IT WORKS !!!
As you may see...
Code:
debian@devuanhdd:~/Downloads$ tar -xvzf vuex3295.tgz
VueScan/
VueScan/vuescan
VueScan/vuescan.8ba
VueScan/vuescan.svg
VueScan/vuescan.ds
debian@devuanhdd:~/Downloads$ cd VueScan/
debian@devuanhdd:~/Downloads/VueScan$ ls
vuescan vuescan.8ba vuescan.ds vuescan.svg
debian@devuanhdd:~/Downloads/VueScan$ su
Password:
root@devuanhdd:/home/debian/Downloads/VueScan# ./vuescan

You just don't get it. It may work with many scanners, but it does NOT work with
every scanner, even some made by HP.
That second quote in my previous message was directly from the vuescan software.
Well, I just downloaded VueScan and it does work, but apparently it's not free. Scanned images have a visible watermark on them which is unacceptable in many instances. To have a clean image sans watermark you have to pay for the package. For my purposes, however, it appears that VueScan has a lot of features that I would never use and that makes it more complicated to use. I had to play around with it a bit to figure out how to scan images and then save them. I'm sure it's a great program for many purposes but for simple scanning it's a bit much. And also there's a cost involved which, incidentally,I could never figure out what that was!
No, it is a commercial product. The demo mode is just so that you as the user can decide if it is working for you (hence the watermark). If it meets your requirements then you proceed to purchasing the license. The cost is mentioned here.
