plustek: Thread: Problems with Kernel 2.6.4 (SuSE 9.1)

Hi, 
 
I have problems installing the sane-backend for the Plustek OpticPro 
4800P. 
 
First, I tried  
 
[direct] 
device parport0 
 
in /etc/sane.d/plustek_pp.conf 
 
This results in: 
# scanimage -d plustek_pp:/dev/parport0 
scanimage: open of device plustek_pp:/dev/parport0 failed: Error during 
device I/O 
 
and  
#dmesg 
ppdev: user-space parallel port driver 
ppdev0: claim the port first 
ppdev0: claim the port first 
ppdev0: claim the port first 
 
Second: 
Trying to build the kernel-module results in a problem, because in 
src/misc.c, line #834, the function parport_enumerate() has been removed 
from the 2.6.4 kernel. 
 
Any suggestions? 
 
TIA, 
Christof

Hi,

please be more specific, what sane-backends are you using?
Please download the latest snapshot from sane-project.org
Then when using the parport device, make sure you are allowed
to access it. 
To build a kernel-module for kernel 2.6.x, you will need the
sane-backend sources, then go to the directory doc/plustek
and call MakeModule.sh (as root user), this script should do
the rest - but I recommend to use the user-mode backend.

When doing the next tests, please provide the debug output
of the backend:
export SANE_DEBUG_PLUSTEK_PP=20 ; scanimage -L

Ciao,
  Gerhard

I have also a Plustek 4800P and the same problem.

I try to use userland diver and when the backend opens the parport0 device the
kernel answers "ppdev0: claim the port first" and open fails with error code -1.
The log gives versions of sane and backend...

$ ls -l /dev/.static/dev/parport0
crwxrwxrwx  1 root lp 99, 0 2005-04-20 10:46 /dev/.static/dev/parport0

$ export SANE_DEBUG_PLUSTEK_PP=20 ; scanimage -d
plustek_pp:/dev/.static/dev/parport0
