Read from Psu:
The patent, which was filed in February and published in August lists a number of devices that will be compatible with the PS5 when it launches. These devices include the PSVR headset, PlayStation Move controllers, PlayStation camera, Dualshock 4, and mice and keyboards. But, most interestingly the patent also shows the PSP and mentions the PS Vita as being compatible.
