The accessory port found only on the original Vita models is a custom port USB interface.
It is commonly thought that api to enable the port was removed in 1.69 however. This is not true. Even on the latest firmware the accessory port can be enabled using sceUsbServAccessoryActivate and disabled with sceUsbServAccessoryDeactivate.
Offical usage
There are only a few documented uses for the accessory port on the PSVita.
FCC
In the FCC filing for the PDEL-1001 development unit. It seems that some dongle attached to the device is used as part of their hardware testing framework.
Accessory to USB adapter
An Accessory port to USB adapter board was sold on auction sites awhile ago. It comes from a PSVita factory in China that was being repurchased for other things. since production of the PSVita has stopped.
Simular Cables
The sheilding on the port is simular to what is used on the Panasonic K1HA14AD0001 camera.
However. The pin layout on this is incorrect and will short the accessory port if plugged into a psvita.
