STM32 USB-FS-Device firmware library
This section describes the firmware interface(called USB-FS-Device Library)used to
manage the STM32 USB 2.0 full-speed device peripheral. In the rest of the document, it
will be referred to as USB-FS_ Device peripheral
The main purpose of this firmware library is to provide resources to ease the development of
applications for each USB transfer type using the USB-Fs Device peripheral in the STM32
microcontroller families

Figure 1 shows the interaction between the different components of a typical USB
application and the USB-FS Device library
