USB Interface

The CoreModule 920 contains two root USB hubs and six functional USB ports. Four of the six USB ports
are routed through two 10-pin headers (H15 and J25), and the other two ports are routed through the
PCIe/104 interface connector. The PCH provides the USB function including the following features:
•
Supports USB v.2.0 EHCI and USB v.1.1 UHCI
•
Provides over-current detection status
•
Provides a fuse on board for over-current protection
Table 3-6 describes the pin signals of the USB0 and USB1 header which consists of 10 pins, in two rows,
with odd/even (1, 2) pin sequence, and 0.100" (2.54mm) pitch.
