There is a USB client on handheld PS 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, there exists a way to use the port in host mode probably through USB OTG or something similar.

Teardown of PS Vita OLED dock here.

Pin Name Description
1 Power? N/C on cables and DevKit USB Ethernet adaptor, but connected on TestKit USB Ethernet adaptor. Goes to SN99057 pins 31-32.
2 Power? Same net as pin 1
3 Dock Analog Ground (TRRS Pin 3) For stereo audio 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 Syscon UART RX See UART Console
7 Syscon UART TX See UART Console
8 Syscon UART CTS See UART Console
9 Syscon 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 adaptor.
12 Dock TRRS Pin 4 Digital signal. To Syscon (F9). Connected on USB Ethernet adaptor.
13 ? To Syscon (G4). Not seen used anywhere.
14 GND 1 GND on PS Vita and USB Ethernet adaptor. N/C on charging cable and dock.
15 ?Peripheral Detect? To large ceramic chip. 125K pull-down.
16 GND 2 GND on PS Vita. N/C on USB Ethernet adaptor 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 PS Vita and charging cable. N/C on USB Ethernet adaptor. 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. USB OTG is also supported in hardware and software, as there is an Ethernet adaptor containing a micro-USB 2.0 type B connector as well (there exists a rare PTEL-20xx TestKit Ethernet Adapter: https://i.ibb.co/HDNHNDx/image0.jpg)

The "CBPS" also managed to get USB OTG working and was able to mount a USB drive via VitaShell.
