There is a USB client on handheld Vita devices. It uses a proprietary multi-connector on the OLED (PCH-1XXX) units and a micro-USB on the LCD (PCH-2XXX) units.

PCH-1XXX Pinout

UDC male pins.png

Because of the existence of the USB ethernet adaptor, that means there exists a way to use the port in host mode probably through USB OTG or something similar.

Teardown of Vita OLED dock here.

Pin Name Description
1 Power? N/C on cables and devkit USB ethernet, but connected on testkit USB ethernet. Goes to SN99057 pins 31-32
2 Power? Same net as pin 1
3 Analog Ground (TRRS Pin 3) For stereo output
4 Right Channel Audio (TRRS Pin 2) To audio codec IC
5 Left Channel Audio (TRRS Pin 1) To audio codec IC
6 UART RX See UART Console
7 UART TX See UART Console
8 UART CTS See UART Console
9 UART RTS See UART Console
10 Audio? To audio codec IC, not seen used anywhere.
11 Accessory Enable? Digital signal. Pull-down to GND on dock. To Syscon (C11), connected on USB Ethernet
12 TRRS Pin 4 Digital signal. To Syscon (F9), connected on USB Ethernet
13 ? To Syscon (G4), not seen used anywhere.
14 GND 1 GND on Vita and USB ethernet adapter, N/C on charging cable and dock
15 ?Peripheral Detect? To large ceramic chip, 125K pull-down
16 GND 2 GND on Vita, N/C on USB ethernet and charging cable, small cap to USB GND on dock
17 VCC +5V VDC
18 VCC Same net as pin 17
19 GND 3 GND on Vita and charging cable, N/C on USB ethernet, large cap to USB GND on dock
20 D- USB Data
21 D+ USB Data

PCH-2XXX Pinout

Port is a standard micro-USB Type B. Highly likely that USB OTG is supported in hardware although there's no evidence that it's enabled in software.

Pin Name Description
1 VCC +5V VDC
2 D+ USB Data
3 D- USB Data
4 ID USB OTG
5 GND Ground
