hi again,
first, I appologize for the repeat posting of the original message.
second, thanks for the help in recompiling the kernel with ppscsi module
support. This is now working! yippee!....
thirdly, I am having problems getting the scanner to register. I've
think i've read all available documentation (please let me know if there are
other resources) and i am a bit stuck. the scanner does not seem to show
up:
----------------------------------------------------------------------------
-
no scsi devices appear to register. should they be?
do i need to manually echo the scsi/parallel device into this file?
if so, what should that device be?
[root@oort sane-backends-1.0.5]# cat /proc/scsi/scsi
Attached devices: none
----------------------------------------------------------------------------
---[root@oort log]# sane-find-scanner # Note that sane-find-scanner will find any scanner that is connected # to a SCSI bus. It will even find scanners that are not supported # at all by SANE. It won't find a scanner that is connected to a # parallel, USB or other non-SCSI port.
# If your scanner uses SCSI, you must have a driver for your SCSI # adaptor and support for SCSI Generic (sg) in your Operating System # in order for the scanner to be used with SANE. If your scanner is # NOT listed above, check that you have installed the drivers. ---------------------------------------------------------------------------- -
scanimage -L has no output!
[root@oort log]# scanimage --list-devices [root@oort log]# ---------------------------------------------------------------------------- --
these are the instructions on the http://www.torque.net/parport/ppscsi.html page: insmod scsi_mod insmod sg insmod parport insmod parport_pc insmod ppscsi insmod epst
they all work except the last:
[root@oort sane-backends-1.0.5]# insmod epst Using /lib/modules/2.4.2-2/kernel/drivers/scsi/epst.o /lib/modules/2.4.2-2/kernel/drivers/scsi/epst.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
is these irrelavent because i have an HP scanner and the epst module is only for epson scanners?
------------------------------------------------------------------------
here is some log file output:

-------------------------------------------------------------------------
I tried to 'echo "verbose=4"> /proc/scsi/ppscsi/0', but there is no such file: is this the correct way to create more thourough logging? is it an error that the file is missing?
[root@oort sane-backends-1.0.5]# ls -al /proc/scsi total 0 dr-xr-xr-x 2 root root 0 Jul 1 22:38 . dr-xr-xr-x 45 root root 0 Jun 30 15:26 .. -r--r--r-- 1 root root 0 Jul 1 22:38 scsi ---------------------------------------------------------------------------- ---
I tried to load this when loading the module, as stated in ppscsi.c comments, but i get the following error:
[root@oort log]# modprobe ppscsi verbose=4 /lib/modules/2.4.2-2/kernel/drivers/scsi/ppscsi.o: invalid parameter parm_verbose /lib/modules/2.4.2-2/kernel/drivers/scsi/ppscsi.o: insmod /lib/modules/2.4.2-2/kernel/drivers/scsi/ppscsi.o failed /lib/modules/2.4.2-2/kernel/drivers/scsi/ppscsi.o: insmod ppscsi failed

I am really stuck and would really appreaciate help with this. The reason I need this to work is because i would like to write a PHP web app that would execute command line scanimage and write the image to a tmp file, convert to jpg & write to mysql database (along with other info). My only hurdle is getting the hardware and command line scanimage to work. (the scanner would be connected to the webserver, the DB on another linux machine, and the webbrowser would be platform independent).
If anyone is intrested in this program, i would be happy to share my code. I have never written anything that i think would be useful on any sort of big scale, so any guidence on releasing this to the open source, linux community would also be helpful :)
-thanks, fernando pando

Use 'make mrproper' first, then copy a config file (from the configs directory) to .config, and run make oldconfig.

Yes.
