Hey Thomas,
so if this link seems to be correct, your environment
must be broken somewhere else!
I'll try to explain, how the different kernel-versions where detected
in the driver code:
If you have a closer look to the file plustek_driver/h/sysdep-2.1.h
you'll find, that here we try to detect the kernel version by including
the file /usr/src/linux/include/linux/version.h
This file MUST include the correct version code, please check.
For example the file for kernel 2.4.1 looks as follows:
#define UTS_RELEASE "2.4.1"
#define LINUX_VERSION_CODE 132097
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
After decoding this we set some defines, like LINUX_24.
This definition is responsible for choosing the correct PARPORT_MODE_XXX
definitions in file plustek_drivers/src/misc.c (around line 68)...
I'm not sure about your programming skills, but you might have to track
down the problem on your own. I think it must have been something
wrong with your setup. It has been reported, that in some
cases, the kernel headers where not correct etc. Please check
that.
