USB serial console on Ubuntu for my Sheeva Plug

Just some notes for myself on how to connect to my SheevaPlug from my Ubuntu workstation.

You will need to use the command cu, if you don’t have it you can install it;

sudo apt-get install cu

Connect the USB cable to the sheevaplug and your PC.

Run dmesg to see where it’s attached to;


You should see something like this;

[431165.473195] ftdi_sio 2-1.1:1.1: FTDI USB Serial Device converter detected
[431165.473233] usb 2-1.1: Detected FT2232C
[431165.473236] usb 2-1.1: Number of endpoints 2
[431165.473238] usb 2-1.1: Endpoint 1 MaxPacketSize 64
[431165.473241] usb 2-1.1: Endpoint 2 MaxPacketSize 64
[431165.473243] usb 2-1.1: Setting MaxPacketSize 64
[431165.473542] usb 2-1.1: FTDI USB Serial Device converter now attached to ttyUSB0

To connect do;

cu -l /dev/ttyUSB0

If you get something like;

cu: /dev/ttyUSB0: Line in use

You will need to do;

sudo chgrp craig /dev/ttyUSB0

Replace craig with your username (obviously).

Then you will be able to connect with;

cu -l /dev/ttyUSB0
