(old)Puppy Linux Discussion Forum

I have an Epson perfection 1250 and a Canon N670u. The sane-find-scanner command will find both scanners. However scanimage says that there is no sane device found for either scanner. xsane says that there are no sane devices as well. I made sure that the conf files had the appropriate lines uncommented. USBView sees both scanners. Does any body have any ideas?

Did you get any joy with scanning since your post?

I only have a parallel port scanner.

I am currently overhauling the scanning, have just upgraded SANE and Xsane to latest versions.
Perhaps I will borrow a usb scanner, see if I can get it to work.

No luck yet, but I have just finished building my

Well sane doesn't work with the VIA machine either. I saw that you updated the sane and xsane versions. I'm looking forward to trying those.

Hmm, I wonder if there is supposed to be some kernel module loaded for usb scanner access?
Do you have any other Linux distro that you could try from, then run "lsmod" to see what modules are loaded. ...preferably a distro running a 2.4 kernel!

The live CDs that I have are Knoppix 3.7, DSLinux 1.0rc2, and Suse 9.1 Live Eval. I don't know what kernel they use but I could give them a try.

Well I threw in the Knoppix CD and the Canon scanner worked right away. Here is what I got when I ran lsmod.

oops forgot to log in.

Okay I logged in this time.
Suse was using Xsane like Puppy and I got the same errors as I did in Puppy. I ran lsmod any ways and this is what I got.

Hey, Knoppox loaded a module called "scanner"!

Furthermore, I just checked, there is such a module in the original full set of modules. So, if you grab the full modules tarball off ibibilio.org, you should be able to load it.

So, that will have to be in the next Puppy!

Okay, will attach it here...

Not sure if this one is compatible with the 1.0.3 kernel.
Any way give it a go.

# insmod ./scanner.o

should do the trick.

Okay, just do this:
Copy scanner.o.gz to /lib/modules/2.4.27/usb/
(do not uncompress)

Then run depmod:

# depmod

Then you can load it with modprobe:

# modprobe scanner

It works! Both the Canon and the Epson were recognized and worked with xsane. I didn't even have to edit any of the conf files. Great job Barry. Thanks

Okay, one more thing to check.
Can you find out if Xsane loads the scanner module automatically, instead of having to do it manually.

If you already have it loaded, unload it:

# modprobe -r scanner

Um, if you don't have it loaded, running off live-CD, you will have to do those steps again, coz they would have got wiped at a reboot:

Copy scanner.o.gz to /lib/modules/2.4.27/usb/
#depmod

Then run Xsane:
# xsane

...so, wonder how intelligent it is?

Nope, I had to run "# modprobe scanner" manually to get xsane to work., but once it's loaded it's smooth sailing er... scanning

Edit
I'm using the instal to hard drive option2, and after a reboot I have to run " #modprobe scanner" again to get xsane to work. I wonder if there is a way to get it to load when you start xsane?

Yes, and probably have to make sure "parport_pc" module is loaded for parallel port scanner -- it is for me as I have a parallel port printer and the Printer Wizard causes the parport module to get loaded at bootup.

Okay, I gotta finish the Scanner Wizard!
...this should be done by Pup 1.0.4!

Umm, there are such things as SCSI scanners aren't there?
...are these rare enough to pretend there aren't any?

I've heard of them, but have never seen one. I'd say to forget about them unless people request the feature. I'd have no to test and see if it worked either.

Just a thought... Do we really need a scanner wizard since xsane detects the presence and type of scanner automatically (once the module is loaded). Could we just have a script that the xsane start menu points to instead of actually pointing to xsane? The script could then load the module and start xsane.

Yeah that's true, like a simple question, that only has to be asked once "Do you have a usb or parallel-port scanner, or both?" -- or maybe that can be autodetected ...hmm, yes, could be -- the "find scanner" program only works for usb scanners, so if that fails then it either isn't supported or it's a parallel-port scanner ...yeah, no need for a Wizard!

So who's writing the script?
