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.
The only documented usages of this port is from an 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.
As well a Accessory port to USB adapter that appeared on auction sites awhile ago.
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.
