Hello, I am trying to get my scanport sq2030 scanner to work under linux so that I don't have to switch over to windows xp every time I need to use it. I did some research and found out that the kernel must be patched with the ppSCSI patch. I downloaded a kernel source file (tar.gz) from www.kernel.org and patched the kernel with the patch linux-ppscsi-2.6.x-20060424 from penguin-breeder.org I did a make oldconfig and it looked at my existing config file to see what questions were already answered. I answered the rest. After that I compiled the kernel with bzimage. Later I did make modules. When I did the make modules I got an error which is make error [1] and make error[2]:

Next i tried to backup my existing modules and got this error message.
[root@fedoradesktop linux-2.6.24]# mv /lib/modules/`uname -r` /lib/modules/`uname r`.bak
uname: extra operand `r'
Try `uname --help' for more information.
[root@fedoradesktop linux-2.6.24]# uname -r
2.6.23.14-107.fc8 (this is my current kernel)
I tried it a different way.
[root@fedoradesktop linux-2.6.24]# mv /lib/modules/2.6.23.14-107.fc8 /lib/modules/2.6.23.14-107.fc8.bak
mv: cannot stat `/lib/modules/2.6.23.14-107.fc8': No such file or directory
[root@fedoradesktop linux-2.6.24]#
So what do I have to do to get a working patch for the kernel source, (I downloaded kernel 2.6.24) compile the kernel, and install it properly?

- Unless you need to build all the modules, I don't think you'd need to include all those SCSI card drivers for ppSCSI (just sg and scsi_mod?).
- Apparently linux/config.h is renamed to linux/autoconf.h, check your kernel source tree and symlink the file. (also see this LQ thread)
- the second uname should read `uname -r`.

I am using /dev/parport0 in my microtek2.conf; this is what I get from dmesg:
ppdev0: registered pardevice
ppdev0: unregistered pardevice
ppdev0: registered pardevice
ppdev0: unregistered pardevice
ppdev0: claim the port first
ppdev0: claim the port first
ppdev0: claim the port first
ppdev0: claim the port first
ppdev0: claim the port first
ppdev0: claim the port first

I tried lp0 and got console ready
What does that mean?
I think that was happening, because the permissions weren't set.

okay it seems the only error I am getting from the kernel is with epst: no such device. I got the scanport sq2030 to work when I loaded all of the ppscsi modules except epst with modprobe (parport_pc io=0x278 irq=7) I did modprobe onscsi host5=0,0 It detected my scanner 300a4 scsi7 device (I guess this is also called a microtek scanmaker v310) I tried scanimage -L that worked. I did xsane that worked. I did chmod o+x /dev/sga[0-4] (might be sg4 I forget) to set the permissions. Microtek2.conf says /dev/sga4 When I did scanimage microtek2 /dev/sga4 --mode Color > microtek2.jpg It started moving the head making noises then stopped; the lamp turned off (At first it was saying io error). I rebooted. I did vi /proc/scsi/scsi and looked at the devices. My scanner is no longer there. What happened? So I tried modprobe onscsi host5=0,0 again and the terminal just hangs. Is this a termination problem? I have one scanner (I don't think it is terminated) Is it possible to damage it so that the computer no longer sees it. I think I have tried everything. I think the lamp starts moving forward slowly then moves the wrong direction, because it makes an unusual noise, and I am afraid that I will damage it any help would be appreciated.

okay I successfully compiled 2.6.13 and tried to boot it I got kernel panic-not syncing:vfs:unable to mount root fs on unknown-block(0,0). I read a post about using mkinitrd. I tried that and got No module pata_atiixp found for kernel 2.6.13, aborting. I searched for the module and couldn't find it, but I am pretty sure I turned everything on that I could except experimental and turned on all of the modules. What is the deal? kernel 2.6.23.14-107 has this module. I edited ppscsi.c and ppscsi.h and successfully compiled kernel 2.6.23.14 with the ppscsi patch. I made sure not to enable the module that says experimental, because it actually said "This doesn't work yet." I did make modules make modules_install did mkinitrd /initrd-blah-blah blah and edited my grub.conf and it worked! Now what [do I have to do to get my scanport sq2030 working]? This also happened to be the same kernel I am using excluding the - 107 part. In my make oldconfig I didn't have to answer any questions except the ppscsi ones. Okay I insmod(ed) all of those modules in the /etc/rc.d/rc.local and I tried to modprobe them with modprobe e.g. epst and I got FATAL: Error inserting epst (/lib/modules/2.6.23.14/kernel/drivers/scsi/epst.ko): No such device (which is the same thing that I got when I tried the ppscsi-beta2 before I did all of that work compiling the kernel) It appears to work with this in my rc.local:
modprobe scsi_mod
modprobe sg
# modprobe parport
modprobe parport_pc io=0x278 irq=7
modprobe ppscsi
# modprobe epst
# modprobe onscsi
modprobe onscsi host0=0,0
modprobe onscsi host0=0,0
I realized that the resolution has to be set to 50x50 or lower and that you must set it to jpeg 8.5x11.00 inches and it will scan. The image is poor quality. I guess that is, because the resolution was so low. The ppscsi-beta2 seems to work also, before sometimes it did; sometimes it didn't work. I guess you have to recompile ppsci-beta2 for each kernel. I am not sure why, but now I have a custom kernel that works and a yum installed kernel that works with ppscsi. I cannot get it to scan above 50 dpi. In windows you can get 300 dpi. I am just glad my scanner works now... I wonder how long that will last.

You should try setting SANE_SG_BUFFERSIZE variable.

It worked for me with same problem. 8)

bwt, here's a patch for latest 2.6.25 kernel. %)
