+ You can also use a serial FTDI debug board, with GNU Screen (example):<br/>
+ # <b>screen /dev/ttyUSB0 115200</b><br/>

+ show an FTDI debug board in use. With screen you can then login as root, like you would using SSH.<br/>
+ Using this, you can also see text output (from kernel, etc) when booting the machine.

+ You can also simply connect the USB cable from the BBB to another computer and a new network interface will appear,

Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded.
<a href="images/x200/strap.jpg">images/x200/strap.jpg</a> shows how I earthed myself. This is to prevent you
from causing any ESD damage. The surface that you place components on should also be earthed/grounded.
