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. Regards, Clemens |
