Canon MP540 and libusb

[pdc_2]

great;

I wonder if you using 32bit or 64bit Suse;

... I think the command is

uname -r

............

when you look in usr, do you see a directory called lib64 as well as the lib directory that you have found?

[exsencon]

In usr there is only one directory lib.
In it are the 4 items I gave.

When I do uname -r:

zeger@linux-71q9:~> uname -r
2.6.27.7-9-pae

For me libusb is there,maybe when I do rpm -ivh to install the canon scanner drivers he can not find it or it is the wrong libusb
It's a mystery to me.

[pdc_2]

what do you get with the command

getconf -a | grep KERN

(I think it more directly tries to work out 32bit or not ...

[exsencon]

Nothing comes out when i do that

linux-71q9:/home/zeger # getconf -a | grep KERN
linux-71q9:/home/zeger #

[pdc_2]

sorry

try

uname -a

[exsencon]

Here it is:

linux-71q9:/home/zeger # uname -a
Linux linux-71q9 2.6.27.7-9-pae #1 SMP 2008-12-04 18:10:04 +0100 i686 i686 i386 GNU/Linux

I don't see any 32 or 64bit reference

just a add-on
I have a Suse 10.2 installed on a laptop so I tried to install the canon MP520 scanner drivers there just to see if I could. And yes no problem at all and no questions about libusb.
So the problem is suse 11.1 specific.
I don't know what changed between 10.2 and 11.1. I checked the /usr/lib files on suse 10.2 and they look the same as those in 11.1

[pdc_2]

well maybe when you want to scan, you can connect the MP to your laptop? We still run a Canoscan on a 10.2 Suse on one computer;

maybe you report this problem to the folks at Suse; as a bug report? you seem to have defined it very well as someone in 11.1

I don't think we can take it much further now;

all best wishes

I am having the same problem with a Canon MP520 on a 32-bit PC.

My previous openSUSE 11.0 worked perfectly with the Canon scangearmp drivers.

Now that I have installed openSUSE 11.1 I also have the "cannot find libusb" message although all libusbxxx rpms are installed.

I suspect the libsub package has been renamed or is located in another directory with openSUSE 11.1.

Perhaps one of the following knows the answer:

Yes,well...my commiserations.I filed a bug report with suse over this and their answer:

--- Comment #1 from Johannes Meixner <jsmeix@novell.com> 2009-02-11 05:01:06 MST ---
The Canon Pixma MP520 scanner unit is currently not
supported by a SANE scanner driver which we provide
for openSUSE 11.1.

Therefore you wrote
"Canon provides linux drivers for this device".

I.e. you use a third-party scanner driver software.

It is a well known drawback of third-party drivers
that they may no longer work for a new openSUSE version
because of whatever special assumptions in the driver.

We cannot adapt their drivers for a new openSUSE version.

Therefore you must go to Canon and ask them,
if anything goes wrong with their driver
for openSUSE 11.1

My answer to that(but it doesn't really matter)

Well,I really find this unacceptable.If the scanner worked with suse 10.2 and
10.3 it should work with 11.1.Later suse versions (and any other distro for
that matter)are supposed to build and expand on what they have and provide
support for even more devices than in the earlier versions.
The problem is with opensuse 11.1 not with Canon. They provided driversthat
worked with your earlier versions.It is quite normal one should expect they
work with later versions of the OS.This is really bad policy.Bye bye Suse.

So end of story I suppose unless somebody comes up with a solution. I still find their answer amazing and not at all linux-like.
