Accessory Port / EHCI[edit | edit source]

The accessory port found only on the original Vita models is a custom port USB interface.

It is commonly believed that code to enable the port was removed in 1.69 however This is actually not true.

Even on the latest firmware the accessory port can be enabled using

The port is mostly compatible with drivers for the full sized USB Port on the PlayStation TV. Only difference being 3.3v power and logic levels, instead of 5v.

There have been some usage of the accessory port outside Sony

VitaShell[edit | edit source]

VitaShell can mount a USB Mass Storage device plugged into the accessory port. as seen in this video on youtube

Simular Connectors[edit | edit source]

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.
