#include <WutFileSystemDriver.h>

Public Attributes
int	id
	Device enum value (DEVICE_SD, DEVICE_USB, ...)
char	name [16]
	human-readable base name, eg.
char	volumeLabel [16]
	volume label, best-effort - empty if none could be read
char	prefix [32]
	devoptab mount prefix, eg.
char	stablePrefix [32]
	same string as prefix, but set once in init() and never cleared on unmount - this device's identity for path->device resolution (FindDevice()), independent of current mount state
bool	isPresent
	found on the last poll
bool	isMounted
	A filesystem is currently mounted on this slot.
bool	unmountRequired
	The slot was removed or invalidated and must be unmounted before the next mount attempt.
bool	labelFetched
	volume label already looked up since the last mount/removal - see getVolumeLabel()
