Sane Again
 

I have been attempting to configure my Linux (Mandrake 9) to recognise my Canon
CanoScan FB 630u scanner.

Having viewed a number of previous postings (on Scanner installations) on this
forum, I thought it was all going to be relatively easy. I'm not there yet??

I believe I have installed Sane RPM's off the Mandrake CD's ie:
Sane-frontends (1.0.8-1mdk); Sane-backends (1.0.8-5 mdk); XSane
(087-1 mdk); XSane-gimp (.87-1 mdk);LibSane 1 (1.0.8-5 mdk);LibSane 1-devel
(1.0.8-5); LibSane-hpojo

I have taken the following steps:

Established that there is a directory called: /dev/usb/scanner0

Added the line: /sbin/modprobe scanner vendor=0x04a9 product=0x2204 to the end
of the /etc/rc.d/rc.local file

Added the line: options scanner vendor=0x04a9 product=0x2204 to the end of the
/etc/modules.conf file

Added the following two lines to the end of the USB section of
/etc/sane.d/plustek.conf:

[usb] 0x04a9 0x2204
device /dev/usb/scanner0

When I bring-up USB Devices (KDE Control Module) it clearly lists the CanoScan
FB630U as being linked to the USB UHCI Root Hub (1).

When in terminal-mode, upon entering the following commands, these are the
positive responses that get reported back:

scanimage -- version: scanimage <sane-backends> 1.0.8; backend version 1.0.8

sane-find-scanner: found USB scanner <vendor=0x04a9, product=0x2204> at device
/dev/usb/scanner0

ls -al /dev/usb/scanner0: crw ------- 1 tony root 180, 48Jan 3 13:45
/dev/usb/scanner0

However, this is the negative response:

scanimage -L: no scanners were identified (etc etc)

Also, upon entering: xsane the program first brings up the End User Licence
Agreement & following my acceptance I get the error message - xsane: no
devices available.

Any help would be most appreciated.

Try (as root) doing "chmod 666 /dev/usb/scanner0", also it might help if you install libusb and set up usbdevfs.
Hotplugging is another must have for usb devices.

Thanks for the tip Aussie, I'll let you know how it goes.

Most appreciated.

Hi Aussie,

As a follow-up to your suggestions I have:

a) entered the command: chmod 999 /dev/usb/scanner0
b) installed: libusb
c) added the following entry into the /etc/fstab file (after the /proc entry):
none /proc/bus/usb usbdevfs defaults 0 0

I believe Hotplugging is now an integral part of Mandrake ver 9

Unfortunately, I'm still getting the same "No devices available" messages upon entering the Xsane command &
"no scanners were identified" following the scanimage -L command.

Regards,

Tony

Ok, try making a symlink to your device,
"ln -s /dev/usb/scanner0 /dev/usbscanner"
and changing /etc/sane.d/plustek.conf to point to the link.
On my system sane installes the conf files to /usr/local/etc, you may want to have a poke around to see if there are any other sane files that may be conflicting.

Thanks again,

I've made-up the simlink as recommended & edited plustek - trying-out these two configurations:

Example 1:


# The USB section:
# each device needs at least two lines:
# - [usb] vendor-ID and product-ID
# - device devicename
# - CanoScan FBS630u
[usb] 0x04a9 0x2204
device /dev/usbscanner
#
# i.e. for Plustek (0x07B3) UT12/16/24 (0x0017)
# [usb] 0x07B3 0x0017
# device /dev/usbscanner
#
# additionally you can specify some options
# warmup, lOffOnEnd, lampOff
#
# For autodetection use
#[usb]
#device /dev/usb/scanner0


Example 2:


# The USB section:
# each device needs at least two lines:
# - [usb] vendor-ID and product-ID
# - device devicename
# - CanoScan FBS630u
[usb] 0x04a9 0x2204
device /dev/usb/scanner0
#
# i.e. for Plustek (0x07B3) UT12/16/24 (0x0017)
# [usb] 0x07B3 0x0017
# device /dev/usbscanner
#
# additionally you can specify some options
# warmup, lOffOnEnd, lampOff
#
# For autodetection use
#[usb]
#device /dev/usb/scanner0

I've done a 'whereis sane'

& found the following:

/etc/sane.d
/usr/lib/sane
/usr/include/sane
/usr/share/sane

The /usr/include/sane contains two files: sane.h & saneopts.h

and the /usr/share/sane has a subdirectory: xsane containing two text files,
one .rc file, two pnm files & eight .xpm files plus a further subdirectory called doc (containing an assortment of 89 html & jpg files

The /usr/lib/sane directory is the one containing plustek & other scanner drivers.

The 'whereis xsane' shows the directory: /usr/bin

Hi Aussie,

In addition to the last thread, I now find when I type-in the command "sane-find-scanner" I get two devices reported back:

sane-find-scanner: found USB scanner (vendor = 0x04a9, product = 0x2204) at device /dev/usb/scanner0
sane-find-scanner: found USB scanner (vendor = 0x04a9, product = 0x2204) at device /dev/usbscanner

I don't have a dev/usbscanner file or directory.

Also a new icon called: xsane /dev/usb/scanner0 has appeared on the desktop, which if one attempts to remove, the message 'Access denied to /usr/share/apps/kdesktop/Desktop/dynamic-dev-usb-scanner0.desktop' appears. Removing it in root-mode works but it gets remade next time one boots.

What happens when you click on the new icon?

The same: No devices available message

This may be a stupid question, but what happens if you do:
[code]
scanimage -d /dev/usb/scanner0
[/code[

Thanks moses,

I've done that & get the following response:

"You seem to have specified a Unix device name or filename instead of selecting the SANE scanner or image acquisition device you want to use. As an example, you might want "Epson:/dev/sg0" or "hp:/dev/usbscanner0". If any supported devices are installed in your system, you should be able to see a list with "scanimage --list -devices"

When I do this I get: No scanners were identified etc etc...???

Looks like Bill GGGGGGGGGG wins. Who needs this sort of Sh##@@$$????

Many thanks for your suggestion though.

tonyath

Oh, sane wants you to provide the vendor name for the scanner:

Try:
(it may be just "-d canon:/dev/. . .")

copy your /etc/sane.d/plustek.conf to
/etc/sane.d/cannon630u.conf.

Wow, things have really started to happen!!

The command: scanimage -d canon630u:/dev/usb/scanner0 made my scanner jump into gear & go into an initiallation sequence.

This is the first time anything has happened!!

I wasn't quite sure what you meant re the copying process. This is what I did:

I renamed the canon630u.conf file & copied the plustek file into a temp directory. Renamed it : canon630u & pasted it back into the /etc/sane.d directory.

This didn't have any effect when I entered the xsane command (in terminal). I believe (with your help) I'm almost there & appreciate your help.

Kind Regards,

tonyath

Try running either:
or
Also, you'll want to read the man pages:

Hi Moses,

Once again, many thanks for your assistance. This time I got to see what xsane actually looks like.

When I entered the code: xsane canon630u:/dev/usb/scanner0 four windows appear:

When I entered the code: xscanimage canon630u:/dev/usb/scanner0 one window appears:

Now, in both cases these windows appear instantly & when I execute the Aquire function the following error message appears:

Failed to start scanner. Device busy

One of my concerns (see previous postings #5,6 & 7) is the double report-back I get upon entering the code: sane-find-scanner.

This was the result of entering a symlink command: ln -s /dev/usb/scanner0 /dev/usbscanner that Aussie had suggested & it's now starting to bother me.

Is there a way of reversing this command? Perhaps this is now causing a problem.

Regards,

tonyath
