gunzets supports Gunze touch panels under Linux and XFree86. Supported panels are the serial, PS/2, and USB devices.

All devices are supported by means of an XFree86 module, and the USB device via a kernel module as well. Both XFree version 3.3.6 and 4.x are supported, as well as kernel 2.2 and 2.4. The driver is supported by Gunze USA.

Limitations:
Debouncing is only supported for XFree 4.0 (not 3.3.6).
A bounce event breaks smoothing processing
Support for multi-screen operation is not supported.


Compiling

In order to successfully load the module you need to have the following facilities compiled in your kernel or loaded as modules:

usb generic support (usbcore.o)
a usb host controller driver (usb-ohci.o o usb-uhci.o)
support for misc devices like the ps2 mouse (misc.o)
the input mechanism (input.o)

To compile the driver just make. If your 2.4 or 2.2 kernel headers are not available from /usr/src/linux/include then specify KERNELDIR to point to your kernel source directory, either on the make command line or in the environment. For example:

make KERNELDIR=/usr/src/linux-2.4

To load the driver, use insmod:

insmod ./gunzets.o

To use the input mechanism, specify it on the command line:

insmod ./gunzets.o use_input=1

To automatically create the entry point in /dev (needed if you are not using the input mechanism) run the gunzets_load script instead:

./gunzets_load

Instllation

To install the module to the proper places you can run make install. You may also wish to copy gunzets_load from /usr/local/bin to /etc/rc.d/init.d or /etc/init.d and create a proper symbolic link for automatic load at boot.
