Ferrite beads should be attached to the USB cable next to the connectors
– both sides should be installed. In extreme cases ferrite cores may be
added where the cable is looped 3 or 4 times around the core as shown in
figure 8. Cores of 1.5 to 2 inches should be used at both ends of the
cable.
Figure 8 - Example of a USB Cable Using Ferrites
Please refer to the USB Interface Setup section, for an explanation of how
USB works and why EMI may present a problem for this communications
interface.
