4.6.2 General descriptors

The general USB (CODEC) de scriptors describe in general terms the capabilities of the device, like; ‘how many

configurations it supports’, ‘how many interfaces’ etc. A detailed description of these descriptors can be found in

the USB specification [USBSpec]. It layouts a framework to which the additional class specific descriptors can be

integrated. (See paragraph ‘Descriptors’ of the [USBSpec]).

This USB_CODEC supports 4 ‘different’ interfaces. The control, the AudioStreaming out, the AudioStreaming

in and the human interface (HID) are declared in the Configuration Descriptor. The audio interfaces support

different audio topologies see paragraph 4.6.3.1 Audio function topology. It is possible to switch the HID

interface ON or OFF.

Each internal and the external hardware selectable configuration-map has its own Descriptor Map, depending of

the selected Audio topology and the supported HID interface. At start-up time only one Descriptor map can be

implicit selected with a predefined combination of selection diodes. This selection will be discussed in paragraph

4.10.

For each descriptor a column is added to indicate if it is allowed to change the value in the external

configuration-map. The described descriptors are these of configuration-map 1
