The configuration descriptor includes a total length field (offset 2-3) that encompasses all
interface and endpoint descriptors that follow the configuration descriptor. This configu-
ration describes a single interface (offset 4). The host selects this configuration by issuing
a Set_Configuration requests specifying configuration #1 (offset 5).
Interface 0, alternate setting 0 describes endpoint 0 only. This is a zero bandwidth setting.
The interface has no string index.
