Device Enumerator Programmer Notes

Device Enumerators

The DeviceEnumerator is a simple iterator that walks over all connected devices of a specified device class that match a USB VendorID and ProductID. DeviceManagers that derive from DeviceTypeMangager allocate enumerators derived from DeviceEnumerator.

ControllerDeviceEnumerator

Iterates over connected HID controllers of the following types using HIDAPI:

• VID:0x054c/PID:0x03d4 (Vendor:Sony, Product:PSMove)
• VID:0x054c/PID:0x042f (Vendor:Sony, Product:PSNavi)

TrackerDeviceEnumerator

Iterates over connected cameras of the following types using LIBUSB:

• VID:0x1415/PID:0x2000 (Vendor:Sony, Product:PS3EYE)

HMDDeviceEnumerator

Iterates over connected HMDs of the following types using HIDAPI:

• VID:0x2833/PID:0x0021 (Vendor:Oculus, Product:DK2)
