USB Specification 2.0 section 9.5 no. 1:
| If the class or vendor specific descriptors use the same format as
| standard descriptors (e.g., start with a length byte and followed by
| a type byte), they must be returned interleaved with standard
| descriptors in the configuration information returned by
| a GetDescriptor(Configuration) request.  In this case, the class or
| vendor-specific descriptors must follow a related standard descriptor
| they modify or extend.
