Sony is using a similar cryptographic challenge and response scheme for authenticating a PSVR. This means it is almost impossible to clone a PSVR. I am not going to investigate this any further, it's just not worth the effort.

PSVR, PlayStation VR, is sold with a headset and a "processing unit". Some people report that the processing unit can be connected to any HDMI video source but with some caveats. When it is not connected to a PS4 through an USB cable: It is difficult to re-center the screen. It is impossible to adjust the virtual screen size. It is impossible to adjust the screen brightness.

Functions

For now, we are only interested in the functions I've analyzed below. This is enough to make a portable battery powered PSVR "backpack" without a PS4.

Center Screen

Endpoint 4, direction is OUT (host to device), data is 

1B 00 AA 00

Adjust Screen Size/Brightness

My theory is that if the PSVR is showing the USB error icon, sending this HID packet will initialize the screen.

Endpoint 4, direction is OUT (host to device), data is 

21 00 AA 10 XX YY 19 14 00 00 00 00 00 00 ZZ 00 00 00 00 00

Where XX YY changes screen size 

Small:  XX YY = 00 1A
Medium: XX YY = C0 24
Large:  XX YY = C0 32

Where ZZ is screen brightness, a range between 0x00 and 0x20 (0 to 32), in steps of 1 0x00 = dimmest 0x20 = brightest

Volume Buttons

Endpoint 4, direction is IN (device to host), data is 

F0 00 AA 10 XX YY 00 00 00 FF 00 00 02 00 00 00 00 00 00 00

XX is a byte containing bit flags, so far, I can see the earbuds and the mic mute button flags 

No earbuds and unmuted:  XX = 0x87
No earbuds and muted:    XX = 0xA7
Yes earbuds and unmuted: XX = 0x97
Yes earbuds and muted:   XX = 0xB7

YY seems to be the volume, between 0x00 and 0x32 in steps of 2

Head Detector

Endpoint 4, direction is IN (device to host)

Same packet as above in "volume buttons" 

No earbuds and unmuted, head is in:  XX = 0x87
No earbuds and unmuted, head is out: XX = 0x85

Motion Tracking

I can't identify what packet correlates to motion, even when a game is running. There are a few endpoints that look completely encrypted.

Microphone

Endpoint 2 seems to be just 16 bit mic data. That's all I know. Take a look at the descriptor for more info.

Cryptographic Authentication

Sony is using a similar cryptographic challenge and response scheme for authenticating a PSVR. This means it is almost impossible to clone a PSVR. I am not going to investigate this any further, it's just not worth the effort.
