There is a problem on SBC2's purchased before Jan. 10th 2012. There was an issue with some of the routing to the USB hub which can cause issues with certain devices connected to the hub. Particularly bad offenders include servo controllers and X. There are 2 solutions to this problem, you can either contact us and send the device in for modification. Or you can make the modifications yourself provided you have the equipment and the ability to solder small components.
What you will need
If you intend to make the modifications yourself you will need a fine tip soldering iron, a microscope (or very sharp eyes), and a capacitor. The capacitor that needs to be added is as follows:
| Style: | Capcitance: | Package: |
| Surface Mount | 30pF | 0603 |

They can be purchased from Digikey for $0.13 a piece.
What you need to do
The capacitor needs to be added to the board in the location highlighted in red in the images that follow:
