# AAUSBAccessoryMatchingCriteria.InterfaceMatchingCriteria

A structure you provide that enumerates which device interface characteristics to search for.

## Declaration

```swift
struct InterfaceMatchingCriteria
```

## Topics

### Creating an interface characteristics structure

- [init(vendorID:productID:bcdDevice:interfaceNumber:configurationValue:interfaceClass:interfaceSubClass:interfaceProtocol:speed:)](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/init(vendorid:productid:bcddevice:interfacenumber:configurationvalue:interfaceclass:interfacesubclass:interfaceprotocol:speed:).md)

### Interface characteristics

- [bcdDevice](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/bcddevice.md)
- [configurationValue](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/configurationvalue.md)
- [interfaceClass](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/interfaceclass.md)
- [interfaceNumber](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/interfacenumber.md)
- [interfaceProtocol](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/interfaceprotocol.md)
- [interfaceSubClass](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/interfacesubclass.md)
- [productID](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/productid.md)
- [speed](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/speed.md)
- [vendorID](accessoryaccess/aausbaccessorymatchingcriteria/interfacematchingcriteria/vendorid.md)
