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 adaptor, 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? | No known use (N/C on cables, USB ethernet), 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 | ?Headset GND? | 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 large ceramic chip, 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 |
