I am new to this iot envoirment.. I am trying to take a usb card reader into a siemens Iot 2040 and transmit the data to the serial port.
Is that i cant see a usb node in node red. i have tried to install using palette manager and through cmd. But no joy it goes through the process but when i refresh the node red page it is not there.
When i have this usb socket installed will i need to install a usb driver to the iot or will it just read the data and i can just send it out on the serial port??
Any info will be much appreciated.
