The device shows up in the list, but the connection attempt fails immediately.
This is usually due to invalid permissions on the device.

For udev-based systems, you can resolve this by adding rules for the device.

Open a terminal:
cd /etc/udev/rules.d

Create a file to hold the FTDI rules:
sudo nano 40-ftdi.rules

And add the following content to it, save and exit:

#FTDI permissions granted to users group
SUBSYSTEM=="usb", ATTR{idProduct}=="6001", ATTR{idVendor}=="0403", MODE="0777", GROUP="users"
SUBSYSTEM=="usb", ATTRS{idProduct}=="6001", ATTRS{idVendor}=="0403", MODE="0777", GROUP="users"
SUBSYSTEMS=="usb-serial", MODE="0777", GROUP="users"

Reload the rules:
sudo udevadm control --reload

Then unplug the device, plug it back in, and try again.
