The PlayStation 4 Camera runs without user login (kernel/system device?) and depends for many of its system functions on the APU, using a tripple buffering system

Available functions:

  • photo, video
  • depth calculation/imaging
  • pad, move, face, head and hand recognition/tracking
  • one of the cameras can be used for generating the video image, with the other used for motion tracking.

Back chip connected to Aux port is labeled OV00580-B21G-1C. The OmniVision 580 ASIC is not documented, so it seems it was made specially for Sony out of the 500/600 serie (none of them featuring USB 3.0, see external reference).

Front chip connected to microphone array is labeled 5703 324A.

6 iConfiguration 1 0x00 Index of string descriptor describing configuration - set to 0 if no string
7 bmAttributes 1 0x80 Powered by the bus (10000000)

specify power parameters for the configuration :

8-digit bit binary
7|6|5|4|3|2|1|0

  • D0 - D4: Reserved.
  • D5: The configuration supports remote wakeup.
  • D6: The configuration is self-powered and does not use power from the bus.
  • D7: The configuration is powered by the bus.
