STM32L1: IAP via USB

i'd like to extend my STM32L151 device by adding USB bootloading capability. I searched for documentation and examples, but I got the impression that neither of it exists in a complete fashion. To me it seems that there's always some information missing. Mainly I didn't understand which descriptors have to be added or modified.

Does someone know a project that consists of a bootloader and an application with all the necessary descriptors and so on? Some helpful source code would also be great.

Best regards,
