Step 1. First of all, unplug the sensor and plug it in again. Perform dmesg command in your shell. The output should look similar to this:
[1240352.344525] usb 1-1.3: New USB device found, idVendor=1536, idProduct=0101, bcdDevice= 2.00 [1240352.344548] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [1240352.344565] usb 1-1.3: Product: Touch Sensor Module 122 [1240352.344581] usb 1-1.3: Manufacturer: Neonode [1240352.344596] usb 1-1.3: SerialNumber: 1.7.2 [1240352.361097] input: Neonode Touch Sensor Module 122 as /devices/platform/soc/3f980000.usb/usb1/1-1/1-1.3/1-1.3:1.0/0003:1536:0101.0003/input/input8 [1240352.362045] hid-multitouch 0003:1536:0101.0003: input,hiddev96,hidraw0: USB HID v1.11 Device [Neonode Touch Sensor Module 122] on usb-3f9
80000.usb-1.3/input0
It is very important that you can detect the lines in bold above. This indicates correct initiation of the sensor in your OS. If you don't see these lines contact Neonode Support for further assistance.
Step 2. Install Python module evdev: [pip install evdev] For more information see https://python-evdev.readthedocs.io/en/latest/usage.html
Step 3. Run evdev module test program: [python - m evdev.test] This program will give a list of devices connected to the computer. You need to choose the correct device to follow/trace. Example of the output:
1 /dev/input/event1 Neonode Touch Sensor Module 122 usb-3f980000.usb-1.3/input0 1.7.2 => in this case choose number 1.
Step 4. Perform touches. You should see touch notifications in the output window:
