Isolating USB from VBatt on Audiostix2 or Breakoutgs

From GumstixDocsWiki

The Audiostix2, GPSstix, and breakout-gs daughterboards can use power from the Power Jack or the USB client port. The USB bus power (V_BUS on schematics) may conflict with the power jack input (V_BATT) if both the USB and the power input are used. By removing a ferrite bead, V_BATT is isolated from V_BUS, and the two power supplies will not conflict. The device will use V_BATT power only.

On the GPSstix and Audiostix2, remove the ferrite bead labelled FB4.

On the breakout-gs, remove the ferrite bead labelled FB2.
