+-SYMPTOM: "kernel-module version mismatch"
+---------
+-"When I try to "make load" I get an error"
+-
+-/sbin/modprobe pt_drv || exit 1
+-/lib/modules/2.2.14-6.0.6/misc/pt_drv.o: kernel-module version mismatch
+-/lib/modules/2.2.14-6.0.1/misc/pt_drv.o was compiled
+-for kernel version 2.2.14-5.0
+-while this kernel is version 2.2.14-6.0.1.
+-
+-PROBLEM:
+---------
+-You're using the wrong Kernel-header files.
+-
+-The path
+-/usr/include/linux is a link to
+-/usr/src/linux/include/linux and
+-/usr/src/linux is normally a link to your current
+-kernel, i.e:
+-/usr/src/linux-2.2.14
+-
+-If you now upgrade your kernel and you have
+-forgotten to correct the link /usr/src/linux, then
+-every kernel-module you build outside the
+-kernelsource structure will include the wrong
+-version information.
+-
+-SOLUTION:
+----------
+-Set the link /usr/src/linux
+-to your current kernel-source tree before recompiling
+-kernel-modules like pt_drv, then your version mismatch
+-problem should be solved.
+-
+-
+-
+-SYMPTOM: "Device or resource busy"
+---------
+-Any attempt to "modprobe" or "make load" the driver leads
+-to this message.
+-
+-PROBLEM:
+---------
+-The driver refuses to load. During startup, the driver performs
+-some tests according to the parallel port and the connected
+-scanners.
+-If the parallel port is not supported or the scanner cannot be
+-found, the driver returns an error and the system will report
+-"device or resource busy"
+-
+-SOLUTION:
+----------
+-There's no way to provide a general solution. First of all
+-you should check your connections and the parallel port.
+-Also check power for your scanner.
+-If the problem still exists, enable the debug-messages of the
+-pt_drv module (see INSTALL).
+-Then check the messages after loading or send the output to
+-the mailing list.
+-Most of these problems are related to HW-problems. Before
+-giving up, check the scanner under Windows (not really a
+-good advice I know, but it helps to find HW-damage).
+-There was also one case were the internal plugs of the parport
+-connection were wrong...
+-
+-
+-
+-SYMPTOM: "Unresolved symbols"
+---------
+-"make load" or "modprobe pt_drv" produces this message:
+-
+-/sbin/modprobe pt_drv || exit 1
+-/lib/modules/2.2.14-5.0/misc/pt_drv.o: unresolved symbol parport_unregister_device
+-/lib/modules/2.2.14-5.0/misc/pt_drv.o: unresolved symbol parport_enumerate
+-/lib/modules/2.2.14-5.0/misc/pt_drv.o: unresolved symbol parport_register_device
+-/lib/modules/2.2.14-5.0/misc/pt_drv.o: unresolved symbol parport_claim
+-/lib/modules/2.2.14-5.0/misc/pt_drv.o: unresolved symbol parport_release
+-/lib/modules/2.2.14-5.0/misc/pt_drv.o: insmod
+-/lib/modules/2.2.14-5.0/misc/pt_drv.o failed
+-
+-
+-PROBLEM:
+---------
+-The driver needs at least the parport_pc and the parport modules
+-to work. They MUST be loaded prior to pt_drv. If these modules
+-are not loaded you get this message.
+-
+-SOLUTION:
+----------
+-Simply load the parport module. You can add this dependency to
+-your /etc/modules.conf (or /etc/conf.modules) file (see INSTALL).
+-Then every time you load pt_drv with modprobe, parport will be loaded
+-automatically. After modifying this file, call
+-depmod -va
+-
+-

+     now the Acquire Image menu entry. That's all.
+     If not, start gimp from an xterm and have a look at the output.
+ 
+-
+-Q:  Is there any way to load the plustek_driver at bootup-time?
+-
+-A:  Normally, there is no need to do so, because once you
+-    altered your /etc/conf.modules file (or /etc/modules.conf)
+-    and added the suggested stuff (see INSTALL file), you won't
+-    have to worry about loading the driver. It happens automagically. ;-)
+-    The driver will be loaded when needed (and eventually
+-    removed after a specific time of not using it).
+-
+-    Nevertheless, another possibility is to do a modprobe pt_drv in the
+-    /etc/rc.d/boot.local (using SuSE) or
+-    /etc/rc.d/rc.local (using RedHat or Mandrake) file
+-    So the driver will be loaded at bootup-time...
+-    !!! YOUR SCANNER MUST BE ONLINE during power-up then !!!
+-
+-
+ Q:  I wonder if Mandrake 7.1's sane rpm file has this support already built in.
+     My scanner light is coming on yet Xscanimage seems to report that there
+     is no scanner present.

+ ====================================================================
+ 
+-
+ Beginning with SANE-1.0.13, there's a backend called plustek_pp.
+ This is for controlling Plustek parallel-port scanner and compatible
+ devices. For a full listing, see plustek_pp.desc.
+ 
+-This code formerly was available for creating the Linux kernelmodule
+-pt_drv. This should no longer be necessary. You should be able to use
++This code formerly was available for creating the Linux kernel module
++pt_drv. This is no longer be necessary. You should be able to use
+ the backend out of the box.
+-
+-
+-The kernel module
+------------------
+-
+-As it might be helpful to create and use the kernel-module, this way still
+-exists. It's possible to create this module out of the backend sources
+-in sane-backends/backend. Simply do (as root user)
+-
+-./MakeModule.sh
+-
+-Then the module should be compiled, installed and loaded.
+-
+-Add the following three lines to file /etc/modules.conf
+-
+-alias char-major-40	pt_drv
+-pre-install pt_drv modprobe -k parport
+-options pt_drv lampoff=180 warmup=15 port=0x378 lOffonEnd=0 mov=0 slowIO=1
+-
+-See man page for sane-plustek_pp ("man sane-plustek_pp") for explanation of
+-these options.
+-
+-Now "scanimage -L" should show something like this:
+-device `plustek:/dev/pt_drv' is a Plustek 9630P flatbed scanner
+-
+-
+-Known Problems:
+----------------
+-
+-Sometimes it is necessary to change the ioctl-interface between the
+-driver and the backend, in this case the version number of the communication
+-protocol will be changed and newer drivers won't work with older backends
+-and vice versa.
+-In this case (error -9019 in the SANE debug output!!) you have to recompile SANE
+-AND the driver (have a look at the installation procedure above).
