When in USB emulation modes 0, 2 & 4, the Quadstick also appears on the USB bus as a small removable storage device, a Flash drive. This drive is used to hold the customized configuration files the user may wish to use for a particular game or for updating the internal software (firmware) that runs the Quadstick. The flash drive is not available to a PC when the Quadstick is emulating the DS3, XBox 360, or Nintendo Switch controllers.
