+# Why O-3000
+O-3000 is our answer to rigid and inflexible vision solutions. Maybe you know that. The camera you'd like to use
+does not support your (embedded) operating system. The interface specification is top secret and certainly you won't
+get any driver source code. Due to such experiences we developed the O-3000 cameras. In the meantime, O-3000
+has grown into a comprehensive vision system. Everything is open-source and all interface specifications are
+freely available. These cameras are developed and produced in Switzerland.
+
+## USB Host Driver
+This USB driver is needed to communicate with the camera.
+
+### Build and install
+```
+git clone https://stettbacher.ch/gitlab/o-3000/driver.git
+cd driver
+mkdir build
+cd build
+cmake ..
+sudo make install
+```
+
+
+### Cross-Compile
+First a toolchain file is needed to specify the cross-compiler environment. As astarting point,
+use the template 'cmake/toolchain_file_template.cmake'. Specify the cross-compiler and path.
+Run cmake within build directory as follow:
+
+```
+cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchain_file_template.cmake ..
+```
