System BIOS

The BIOS must map the integrated USB3 port to the R200 and report the location for

each camera. The BIOS must declare the R200 power resource methods and creates

an interface to directly control the power resource and interrupt pin through a GPIO.

9.1

UPC (USB Port Capabilities)

The USB3 port in the USB port allocation must be a non-companion port.

PLD (Physical Device Location)

An independent _PLD table must be mapped to each camera’s address. The address

(_ADR) for the color camera (offset 0x0) and infrared camera (offset 0x2) are

dependent on the USB port that the R200 is mapped.

For example, if the R200 was mapped to USB port 15 (0x0F), the color camera _ADR

value is 0x0F and infrared camera _ADR value is 0x11. The UVC OS Address property

can be used to verify this value.
