RS232 serial to USB adapter don't work on NI-cRIO-9030

[DanaPepito]

Dear All,

I brought NI-cRIO-9030 and I just connected to production machine. I need to use 2 serial ports for  this machine. First port for receive data from machine and second port for input serial/ part number by scanning.  I used RJ50 Serial Connector to DB9 for a first one and it has been working well. So, I have to use USB port connected RS232 serial to USB adapter for my scanner (My machine required RS232) but it doesn't work. How do I can use this port for my scanner?  

Thanks!

RS-232 to USB adapter are in many different flavors with many different controller chips used inside. Some use the USB-CDC profile which is a serial communication interface and Linux supports that usually too. Others are build around the FTDI chip which uses its own proprietary USB protocol but Linux has drivers for that too. For other adapters you may have to go on driver hunt.

Another possible problem is the automatic detection of the hardware and the installation of it in the system device tree. You will have to do some Linux console level typing to see if the hardware is even recognized and if it is, why it is not properly mounted.
