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). + + + -- cgit v1.2.3
