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

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

Pin Name Description
1 Power? GND on cables, goes to SN99057 pins 31-32
2 Power? Same net as pin 1
3 Host detect? GND on Vita and charger cable, connected to something on USB ethernet adapter
4 Digital audio out To audio codec IC
5 Digital audio out Same net as pin 4
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
11 ? To Syscon
12 Headset? To Syscon
13 ? To Syscon
14 GND? GND on Vita and USB ethernet adapter, N/C on charging cable
15 Peripheral Detect? To PMIC, 125K pull-down
16 GND GND on Vita, N/C on USB ethernet and charging cable
17 VCC +5V VDC
18 VCC Same net as pin 17
19 GND GND on Vita and charging cable, N/C on USB ethernet
20 D- USB Data
21 D+ USB Data

PCH-2XXX Pinout

Port is a standard USB micro. 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
