I recently started working the , an Open Source Hardware Single Board Computer (SBC). For those not familiar:
BeagleBone is a low-cost credit-card-sized Linux computer that connects with the Internet and runs software such as Android 4.0 and Ubuntu. With plenty of I/O and processing power for real-time analysis provided by the TI Sitara™ AM335x ARM® Cortex™-A8 processor, BeagleBone can be complemented with cape plug-in boards which augment BeagleBone’s functionality.

The Bone does come with a preloaded microSD card with Angstrom (the default Linux distro for the Bone). However, I wanted to make sure I had the latest software, so I downloaded the latest Angstrom image and flashed it onto the microSD card. The BeagleBone Quick Start Guide has more info on how to do that.
Next, I connected the BeagleBone to the USB port on my laptop (running Ubuntu Linux 12.04). This provides power to the Bone which then boots up off the microSD card. The BeagleBone initially shows up as a USB mass storage device:
The contents include drivers for Windows users to continue with the next step. Luckily, no additional drivers are needed for Linux:
Upon ejecting the BeagleBone USB mass storage device, the BeagleBone will then appear as Ethernet-over-USB interface:
afustini@lappy486:~$ ifconfig eth1

The kernel messages on my laptop:

This allowed me to then ssh into the BeagleBone:

Here's a screenshot:
The BeagleBone also presents it's self as a USB serial device, too. A terminal emulator (I use gtkterm on Linux) can then connect to the BeagleBone's console.
