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 |
