Device Configuration File
The device file is needed to define a specific order in which the driver ad-
dresses the touch controllers. This is important to configure multi-screen
setups. The file is located at
/etc/opt/wn/wntouch/devices
. It can be
created by the configuration tool (see above).
It has to contain the sysfs_paths of the devices to be handled by the driver
daemon, which represent the USB ports the touch devices are connected
to. These are handed to the daemon as command line parameters by the
daemon start script.
The device file should be empty in case only one touch screen is connect-
ed to the system.
The devices configuration file needs to be created again if there is any
change in the USB port configuration.
If you intend to create it manually, you can run (as administrator)
>>
/opt/wn/wntouch/sbin/wntouch --list >
/etc/opt/wn/wntouch/devices
to get a list of supported devices in the devices file, and then deleted the
devices you don't need or want.
/etc/opt/wn/wntouch/devices
example:
/sys/devices/pci0000:00/0000:00:1a.7/usb1/1-2/1-2.2/1-
2.2.1/1-2.2.1:1.0
/sys/devices/pci0000:00/0000:00:1a.7/usb1/1-2/1-2.1/1-
2.1.1/1-2.1.1:1.0
