Trying to connect Ardweeny using USB and FTDI board on Linux LXLE

lsusb indicates Linux does not see the usb serial device. The only thing it sees is the mouse. What kind of computer are you using?

Try a different USB cable and and different USB port. USB 3.0 ports may not work so the computer has USB 3.0 ports, try a USB 2.0 hub.
