Canon MP540 and libusb

[RCCrouch]

The scanner drivers that are posted at Canon are incompatible with 11.1 x86_64, not sure about 32 bit. Besides Kooka is a far better app than ScanGear. I have an MP210 and to provide support for it I did the following.

Please advise the bug number. Third-party drivers or not - one of the fundamental policies of the linux development is that all changes must be backward compatible.

The libusb supplied with openSUSE 11.1 is not backwards compatible with the libraries supplied with openSUSE 10.1, 10.3 and 11.0...

i wonder if those having trouble with what they perceive is the location of lsusb could report the results of the command

whereis lsusb

for example on our 11.0 system, 32bit we get

whereis lsusb
lsusb: /usr/bin/lsusb /usr/sbin/lsusb /usr/bin/X11/lsusb /usr/share/man/man8/lsusb.8.gz

Bug number 469248

I still find this unacceptable. I am running 14 linux distros which I regularly upgrade or reinstall to a newer version and all of them (Ubuntu,Mint,Mepis,Fedora,Debian,PCLinux,Mandriva etc)have the scanner end of my MP520 running except Suse in 11.1.
I am pretty sure it all depends on a tiny lib change or something like that. Bad policy.

BTW when I do whereis lsusb I get:

whereis lsusb
lsusb: /usr/bin/lsusb /usr/sbin/lsusb /usr/bin/X11/lsusb /usr/share/man/man8/lsusb.8.gz

Which is exactly the same thing as you got.

The scan drivers require "libusb", I have all libusb-xxx packages installed on both a 32-bit PC and a 64-bit Notebook.

On both computers "whereis libusb" gives...

user@linux:~> whereis libusb
libusb:
user@linux:~>

Does this mean that the symbolic links are missing from the packages?

on our 32bit 11.0 system

when I type in

whereis libusb

I get

libusb: /usr/lib/libusb.la /usr/lib/libusb.a /usr/lib/libusb.so

Hallo Busy Penguin

Your findings agree with many users comments on this and other forums.

To summarise:

The drivers install without difficulty on openSUSE 10.2, 10.3 and 11.0 - "whereis libusb" returns the paths to the library files.

The drivers do not install on 32-bit and 64-bit openSUSE 11.1 installations as libusb can not be found. (Irrespective of KDE 4.1.3 or 3.5.10 desktop) - "whereis libusb" returns nothing.

The installation of libusb does not seem to be complete on openSUSE 11.1.

The drivers do function correctly on other up-to-date linux distributions such as Ubuntu, Mepis and Fedora.

Unfortunately, judging from the exceedingly rude comments of many openSUSE members, it would appear that there is no interest to correct the libusb rpms.

That's a nice and adequate summary of the problem. We can always wait for the next version of Suse and see if they fixed the problem.It is not hard to fix,but you are right,the interest has to be there...

Hello, i had the same problem today.

I installed it with "rpm -i scangearmp-common-1.20-1.i386.rpm --nodeps".

Then i installed "scangearmp-mp540series-1.20-1.i386.rpm" and restarted udev. Now i can use the scanner with "scangearmp" (just type it into the console), which is provided by "scangearmp-common-1.20-1.i386.rpm". (Note, that you will need GTK to run scangearmp!)


Although YasT doesn't yet recognize it, it works fine with this program.
