# SDL\_HINT\_HIDAPI\_LIBUSB(3)

A variable to control whether HIDAPI uses libusb for device access.

## NAME

SDL\_HINT\_HIDAPI\_LIBUSB - A variable to control whether HIDAPI uses libusb for device access.

## HEADER FILE

Defined in SDL3/SDL\_hints.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**#define SDL\_HINT\_HIDAPI\_LIBUSB** *SDL\_HIDAPI\_LIBUSB"*

## DESCRIPTION

By default libusb will only be used for a few devices that require direct USB access, and this can be controlled with

**SDL\_HINT\_HIDAPI\_LIBUSB\_WHITELIST** .

The variable can be set to the following values:

• "0": HIDAPI will not use libusb for device access.

• "1": HIDAPI will use libusb for device access if available. (default)

This hint should be set before SDL is initialized.

## AVAILABILITY

This hint is available since SDL 3.2.0.
