I connected the 4-20mA.ker to a 12v PSU.
The green led is blinking.
However when I connect the USB to my computer nothing happens. It is not detecting the device and in Arduino IDE the TTYUsb port is not shown.
What can be the issue ?
Thanks for your support,
edit: was trying to connect to a Chromebook. This is the device I am using for Arduino but switching to a Windows machine worked.
