vitastick is a plugin and an application that lets you use a PSVita as a USB controller. It uses the UDCD (USB Device Controller Driver) infrastructure in the kernel to simulate such controller, and thus, the host thinks the PSVita is a legit USB gamepad.

Features:

When the VPK is activated, it reduces the clock frequencies to reduce power consumption
Installation:

Add vitastick.skprx to taiHEN's config (ux0:/tai/config.txt):
*KERNEL
ux0:tai/vitastick.skprx
Install vitastick.vpk
Usage:

Open the VPK and the Vita should switch to USB controller mode
Note: If you use Mai, don't put the plugin inside ux0:/plugins because Mai will load all stuff you put in there...
