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.
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 | Dock Analog Ground (TRRS Pin 3) | For stereo output |
| 4 | Dock Right Channel Audio (TRRS Pin 2) | To audio codec IC |
| 5 | Dock 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 | Dock 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, and software as there is an ethernet adapter containing a micro-USB 2.0 type B connector as well (there exists a rare PTEL-20xx Testkit Ethernet Adapter: https://imgur.com/gallery/72rMX96).
| Pin | Name | Description |
|---|---|---|
| 1 | VCC | +5V VDC |
| 2 | D+ | USB Data |
| 3 | D- | USB Data |
| 4 | ID | USB OTG |
| 5 | GND | Ground |
