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.
