HP scanJet 4c and SCSI Symbios Logic 53C416 card not detected

HP scanJet 4c and SCSI Symbios Logic 53C416 card not detected

Post by Marc Nadea » Mon, 07 Mar 2005 08:47:47



A friend of mine gave me a used HP scanJet 4c scanner.

With the scanner comes a SCSI Symbios Logic 53C416 card.

I searched on google and did the folowing (as root):

modprobe sym53c41

Added to lilo.conf in the appropriate section:

append="ncr53c416=0xff80,11 devfs=mount acpi=ht resume=/dev/hda1
splash=silent"

Done a /sbin/lilo

Reboot.

dmesg | grep SCSI gives:

SCSI subsystem initialized

But the card is not listed in Hardrake and it can't detect the scanner.

Did i miss something?

TIA

The scanner is supported by SANE at:

http://www.sane-project.org/sane-mfgs.html

Do not forget proper termination on the SCSI bus!!

So you loaded the module. If the module at that time found the hardware it
would probably print some message which could be seen with "dmesg".

The above append is a message to the kernel, assuming that the kernel has
the driver built in and not loaded as a module. You are now also using
another driver (ncr* instead of sym*). I'm not familiar with your card and
don't know which driver is the best.

Most likely your kernel does not have built in support for the ncr driver.
After your reboot the sym driver loaded with modprobe will be lost and
will have to be loaded with modprobe or in some other way to be usable
again.

Your kernel probably don't have support compiled in for the card. There is
no reason to recompile your kernel, instead you should use a module which
your distribution probably already has precompiled. Depending on your
distribution the module might be loaded automatically with hotplug or you
might have to add it manually in some way by adding a modprobe line to
some startup script.

Henrik Carlqvist a crit:

Actually it was sym53c416

Changed the line for append="sym53c416=0xff80,11 devfs=mount acpi=ht
resume=/dev/hda1splash=silent"

I am not sure that this line is necessary and will

Actually, i was surptised not to find a /dex/sg0 entry.

What id did

modprobe sg
modprobe sym53c41
/sbin/lilo
reboot

The scanner nor the card is still detected

So

Retyped the two modprobe lines

Started x-scan

Miracle.

It works, the scanner seems fully supported and compared to my usb agfa
scanner it's so faaaast...

That is was i did next, a simple bash script in the rc.d and related dirs.

Hope my experience be helpful for somebody else.

Thanks for helping.

Thanks to wmreinemer also.

1. HP ScanJet 5p(Symbios Logic 53C416)

Recently, I purchased HP ScanJet 5p which came with the Symbios Logic
53C416 SCSI adapter. I installed Gimp and SANE to my Linux 2.0.30.

I think I need a low-level driver for this adapter.
Someone recommended me to get another SCSI adapter. But I don't want to.

Please help me find a driver.

Thanks, in advance
