[SOLVED] Is it possible to build ppscsi + onscsi kernel modules into 3.10.17?

Hi guys.

Recently I acquired an old Scanner Microtek Slimscan C3 parport version, and happen to have an low-end mobo with a working port: F1A55-M LX Plus, I've been digging info on the web and I think it could work but I need your advise on how to proceed, should I try downgrading to an earlier distro with the supported 2.6.x kernel or is there a way to make it work with my current kernel distro?: Slackware64 14.1 default kernel.

I haven't found any info about it since I'm guessing this port is dropped on most modern PCs

man page info: sane-microtek2
and the sites linked as reference http://cyberelk.net/tim/parport/ppscsi.html and http://penguin-breeder.org/kernel/download/

Thanks in advance for any suggestion.

SANE and the Kernel should support your device by default, but the backend port is unmaintained.

You might want to check the kernel configuration for the Parallel port driver modules and enable them if necessary, if they are disabled.

Thanks for your prompt reply ReaperX7, I think the problem lies on my end. After modifying BIOS settings, It seems that my mobo won't change parport modes effectively into EPP, EPP or ECP+EPP and since the EPP is required in order to work with this scanner then I'll need to try It on an older mobo.

After checking with a script from: http://umax1220p.sourceforge.net/trouble.html

Code:

# /home/bert/Downloads/parport/ppdiag2

S01: parport built as module
 
S02: parport0:
S02:	modes:PCSPP,TRISTATE
S02:	ADDR :0x378
S02:	IRQ  :5
S02:	DMA  :1
 
S03: parport parameters are: /sbin/modprobe -q parport_pc 2> /dev/null
 
S10: ppdev built as module
 
S12: /dev/parport0 exists ...
S12: /dev/parport0 is readable ...
S12: /dev/parport0 is writable ...
S12: do you want to allow any user to access ppdev ? (yes/no)
yes
S12: mode changed ...
 
successfull end ....


#rmmod parport_pc

#modprobe parport_pc io=0x378 irq=5 io_hi=0x400 dma=none

#dmesg

[ 2402.208168] parport 0x378 (WARNING): CTR: wrote 0x0c, read 0xff
[ 2402.208177] parport 0x378 (WARNING): DATA: wrote 0xaa, read 0xff
[ 2402.208178] parport 0x378: You gave this address, but there is probably no parallel port there!
[ 2402.208196] parport0: PC-style at 0x378, irq 5 [PCSPP,TRISTATE]
[ 2402.210651] ppdev: user-space parallel port driver

The available options on the BIOS setup are Default,EPP,ECP, EPP+ECP, and won't let change them from IO=378h, IRQ=5, DMA=1

I don't know if this count as a solution, but since I lack the skill to hack the code to update the backend, I reused some old PCs one with Win95 Pentium MMX, and other with WinXP Pentium 4, the won't work flawlessly but they are up, they still need software to scan the images but at least the scanner is online.
