* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
* be called whenever the core clock is changed
* during program execution.
*
* 2. After each device reset the HSI (8 MHz) is used as system clock source.

* This driver implements the following aspects of the specification:
* - The Boot Interface Subclass
* - The Mouse protocol
* - Usage Page : Generic Desktop
* - Usage : Joystick
* - Collection : Application
*
* @note In HS mode and when the DMA is used, all variables and data structures
* dealing with the DMA during the transaction process should be 32-bit aligned.

// this way of describing and sending media control is convenient
// short descriptor that permit all kidn meda by sending "usage" code
// see usb hid spec for full list
// it is possible to define one media key per bit it requires more space
// for descripotor and report ending is tighlyu couple to decriptor
// so it is not as convenient
// one such working code can be find here https://github.com/markwj/hidmedia/blob/master/hidmedia.X/usb_descriptors.c
