How to install FTDI driver in DB410C running Windows 10 IOT core RRS feed

  • Question

  • I need to have four virtual COM ports on a Dragonboard 410C that is running Winodws 10 IOT core.  I would like to use a FTDI 1x4 USB-to_RS232 adapter to do this.  When I plug the FTDI adapter into the DB410C, Windows IOT recognizes it and correctly displays that it is connected.  But if I try to write to one of the ports it doesn't work, presumably because there is no built in driver in Windows IOT that allows this.  I get a System.AccessViolationDException: Attempt to read or write protected memory. 

    I assume I need to install a FTDI driver, but I have found conflicting information about this.  I have read that FTDI drivers no longer work with Windows IOT.  Is this true?  If not, which FTDI driver do I need and how do I install the driver in Windows IOT? These FTDI drivers seem complicated.  They have several files and appear to install themselves on operating systems only if they recognize the system. 

    If the FTDI drivers don't work with Windows IOT is there some other company that makes a USB-to-RS232 adapter that does have a driver that works with Windows IOT?

  • Hello, Chuck

    Yes, FTDI is not officially supported by Windows 10 IoT Core. However, you can refer to our MVP - David's Blog article about how to install the driver:

    Win 10 IoT Core: FTDI Serial Driver

    If you want to use USB-Serial TTL module, CP2102 is supported. 

    You can refer to this official docs: Hardware compatibility list

    Good luck!

    Keep Fighting
