USB
The USB interface on the EBX-11 is OHCI (Open Host Controller Interface) and EHCI (Enhance
Host Controller Interface) compatible, which provides a common industry software/hardware
interface. There are four USB ports, one at connector J20, one at J21, and two at J10. The J20
and J21 connectors are standard USB Series A sockets. The USB interfaces at J10 are connected
using the CBR-4004 screw terminal board (pinout below) or a custom cable.
BIOS C
ONFIGURATION
The USB controller can be enabled or disabled in CMOS Setup. The USB controller uses PCI
interrupt "INTD#". CMOS Setup is used to select the IRQ line routed to each PCI interrupt line.
These connectors use IEC 61000-4-2-rated TVS components to help protect against ESD
damage.
On revision 4.01 and earlier boards, one connector (J13) provided the interface to both USB2 and
USB3. The connector was a 2mm 10-pin header. The pinout for this connector is shown below.
