Before the descriptor length was limited to 1024 bytes.

Now it is limited to 65535 bytes, which is the USB maximum for control 

Having a buffer this large by default does not make sense, so a pointer and 
length is the best solution.

The application also sometimes know about what descriptor size(s) it expects.
