# Match Criteria

Specify the criteria that the system uses to match your driver to a device.

## Discussion

When the system detects a new device, it looks for drivers that match the device’s features and capabilities. You specify the features and capabilities that your driver supports using the `IOKitPersonalities` key of your driver’s `Info.plist` file. The `IOKitPersonalities` key contains the array of driver personality dictionaries, the keys of which correspond to device-specific attributes. For example, you might specify the HID usage types that your driver supports.

The keys below are constants defined in the `IOHIDDeviceKeys.h` header file of HIDDriverKit. To match against a specific key, include the value of the key in the personality dictionary. For example, to match against `kIOHIDPrimaryUsageKey`, include the `PrimaryUsage` string in your `Info.plist` file.
