+====================================================================
+
+
+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
+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).
