USB-serial FTDI adapters on Intel Edison

  1. plug USB-serial adapter into Intel Edison USB OTG host port
  2. Check if new device is seen, from Edison terminal:
    dmesg
    
  3. If there isn’t a new assignment to /dev/ttyUSB*, the FTDI kernel module may be needed.
    opkg install kernel-module-ftdi-sio
    

    This assumes you have already setup the Intel Edison opkg repository.

Verify USB-serial adapter

  1. in Edison terminal

     dmesg
    
  2. Reply should include

    usb: FTDI USB Serial Device converter now attached to ttyUSB0

You may have to update your kernel if this doesn’t work.
