Um, have you tried rebuilding ppscsi?

Yes, that's what I do everytime after building a new kernel.
I even switched to ppscsi-beta2-20060424.

I have nothing to offer but to suggest contacting the ppscsi developers.

Does this solution work on Plustek scanners? And if it works, in my case my scanner scans negatives, will this work too? Thanks.

Hi.

First of all, I don't know which modules to load. I tried to load them all and it stuck on sparcsi.ko.

If I lunch xsane, will open with the tv card selected :P

Anyone actually got a plustek working on 2.6?

Hi,

your patch is great, it solved half of my problem! But I still have one. I'm using Kernel 2.6.22 and I get the following error:
Code:

make -C /lib/modules/`uname -r`/build M=`pwd` modules
make[1]: Entering directory `/usr/src/linux-2.6.22-gentoo-r2'

I have re-emerged the linux-headers but there is no config.h! What can I do?

Well, I found the solution, and it's quit easy. /lib/modules/"kernel-version/build/linux/config.h got renamed to autoconf.h around kernel 2.6.19. My last kernel (before 2.6.22) was 2.6.18... So I created a patch. The first part (which changes ppscsi.c) is identical to what you already found out in this thread. The second part changes ppscsi.h:

Code:

Can anyone post a newer patch for gentoo-sources 2.6.25? The posted patches only work until 2.6.24.

It worked for me on 2.6.25.4.

Apply it on http://penguin-breeder.org/kernel/download/ppscsi-beta2-20060424.tar.gz after http://www.kivela.net/jaska/projects/ubuntu-ppscsi/ppscsi-beta2-for-2.6.24.diff.txt (http://www.kivela.net/jaska/projects/ubuntu-ppscsi).

I'm not a kernel hacker, I just found a similiar patch here: :D

For anyone who's interested, I created a tarball with all the combined patches along with the latest patch (modified for older kernel support). It works with 2.6.25 as well as < 2.6.25.

Anyone have any idea how to fix this compile warning? I'd like to have this work for 2.6.28.

For kernel 2.6.32, I got it to work like the Ubuntu guys did. First, make sure you have the following kernel options enabled (you might also need some of the other options):
Code:

Device Drivers -->
    Parallel Port Support -->
        [*] PC-style Hardware


The Ubuntu guys used a Tutorial from an italian page, which basically said to do this:

Code:

wget http://penguin-breeder.org/kernel/download/ppscsi-beta2-20060424.tar.gz
wget http://www.iadegesso.netsons.org/assets/files/ppscsi-patch-2_6_27up.tar.gz
tar xf ppscsi-beta2-20060424.tar.gz
tar xf ppscsi-patch-2_6_27up.tar.gz
mv ppscsi.*.patch ppscsi-beta2
cd ppscsi-beta2
patch -Np1 -i ppscsi.c.patch
patch -Np0 -i ppscsi.h.patch
make


You can then insmod the modules in the directory where you compiled them and/or add the modules to your configuration permanently if you want:
Code:

mkdir /lib/modules/`uname -r`/kernel/drivers/parport
cp ppscsi.ko epst.ko /lib/modules/`uname -r`/kernel/drivers/parport
depmod
echo "" >> /etc/conf.d/modules
echo "modules_2_6=\"${modules_2_6} ppscsi\"" >> /etc/conf.d/modules
echo "module_ppscsi_args_2_6=\"\"" >> /etc/conf.d/modules
echo "" >> /etc/conf.d/modules
echo "modules_2_6=\"${modules_2_6} epst\"" >> /etc/conf.d/modules
echo "module_epst_args_2_6=\"\"" >> /etc/conf.d/modules

Looks like it still doesn't work on kernels > 2.6.30. ppscsi loads without a problem, but loading epst.ko hangs without any notification. I guess it's because of the ppscsi detection that doesn't work. Issuing make always gives the following errors although the modules build:

Code:

  CC [M]  /home/xxx/ppscsi-beta2/ppscsi.o
/home/xxx/ppscsi-beta2/ppscsi.c: In function ‘ppsc_cleanup’:
/home/xxx/ppscsi-beta2/ppscsi.c:849: warning: assignment from incompatible pointer type

Works :D :D :D I got my HP Scanjet 5100c back to work on Kernel 2.6.32. epst.ko takes a while to load, but it does. And Skanlite (KDE) is a great app.

Code:

wget http://penguin-breeder.org/kernel/download/ppscsi-beta2-20060424.tar.gz
wget http://infabo.net/wp-content/uploads/2010/01/ppscsi.patch.tar.gz
tar -xzf ppscsi-beta2-20060424.tar.gz
tar -xzf ppscsi.patch.tar.gz
cd ppscsi-beta2
patch -p1 < ../ppscsi.patch
make
mkdir /lib/modules/`uname -r`/kernel/drivers/parport
cp ppscsi.ko epst.ko /lib/modules/`uname -r`/kernel/drivers/parport
depmod -a
modprobe ppscsi
modprobe epst

EDIT: New download location

There is a new patched version that compiles without an error. I got it from here, so you might want to check it out from time to time.

Code:

wget http://homepages.woosh.co.nz/gryphon/files/ppscsi-patched-karmic.tar.gz
tar -zxvf ppscsi-patched-karmic.tar.gz
cd ppscsi-beta2
make
mkdir /lib/modules/`uname -r`/kernel/drivers/parport
cp ppscsi.ko epst.ko /lib/modules/`uname -r`/kernel/drivers/parport
depmod -a
modprobe ppscsi
modprobe epst

Important for kernel 2.6.33:
/usr/src/linux/include/linux/autoconf.h was moved to /usr/src/linux/include/generated/autoconf.h
As a result, in ppscsi.h, change

Code:
#include <linux/autoconf.h>

to

Code:
#include <generated/autoconf.h>

Make sure to change the line noted in the post above, like for kernel 2.6.33. Works fine.
