Hi all,
Whenever I try to use my Canon FB630 USB scanner, with either scanimage or
xsane, it returns a 'Device busy' message.
I'm new to Linux. I started three months ago, and I've tried RH 7.3 (I
upgraded to sane 1.0.8 - RH rpm), RH 8.0 and now Mandrake 9.0. In each case
I haven't been able to get my scanner working under Linux. It works fine
with MS windows.
I'm sticking with Mandrake until I've exhausted all possibilities. This is
the only distribution I've put all this effort into, so if this fails, I can
still go back and retry one of the other distributions.
I'm hoping someone out there can suggest some reason my scanner doesn't work
(returns the 'Device busy' message).
sane-find-scanner now finds it OK, and both scanimage and xsane correctly
identify it as the canon630u usb scanner, but claim it is busy and so won't
scan an image.
I've read all the relevant (usb, canon, etc...) postings from November 2002
till today, and tried most of what's been suggested, but with little
success.
The scanner did work once with the sane 1.0.8 supplied with Mandrake 9.0,
and then no more (after I rebooted).
To get this to work in the first place, I had to:
modprobe scanner vendor=0x04a9 product=0x2204 (I've since added this to the
rc.local file)
which got the 'driver=usbscanner' to appear in /proc/bus/usb/devices.
Edit the canon630u.conf backend to include both:
usb vendor=0x04a9 product=0x2204
/dev/usb/scanner0
dll.conf was OK, but just to be sure to eliminate conflicts, I commented out
(# in front of) all statements except 'canon630u'. I uncommented 'net' to
see if it had any effect, but it didn't.
I have tried editing 'canon630u.conf' to have only one of either
'/dev/usb/scanner0', 'device /dev/usb/scanner0' or 'usb vendor=0x04a9
product=0x2204', and then all combinations of all three, but to no effect.
I even tried '/dev/usbscanner', but to no effect.
I have checked my scanner permissions to ensure that I get crw-rw-rw for
/dev/usb/scanner0, and this is correct.
A clue to the problem may be that every time I boot up, the system changes
this back to crw-------. I don't know where this is set.
Eventually I came to the conclusion that the problem might be with
Mandrake's implementation of sane 1.0.8, so I used gurpmi to uninstall it,
downloaded the sane 1.0.9 backends and xsane 0.90 sources from their
relevant home sites, untarred them into their own directories as user, and
did the './configure', then 'make', then 'make install'. I did the 'make
install' as root, in case there might be a permissions problem. I used
KDE's find file tool and searched for *sane* starting from / and did not
find any other instances of sane or xsane.
I have provided the following file listings and command outputs, as I have
noticed that these are the most requested information by those 'in the know'
(and that's definitely not me!).
This is my existing canon630u.conf file.
[root at localhost root]# cat /usr/local/etc/sane.d/canon630u.conf

This is my existing rc.local file. It's standard Mandrake 9.0 except for
the last two lines. It may be useful?

I apologise for the extremely long-winded post and all the outputs, but I've
only included what I think might help, based on what I've tried and what
I've read in other posts.
Thanks on advance to anyone who's taken the time to go through this, and for
any solutions offered.
