* STM32F3 Family specific USB functionality
*/
/*
* A device that uses an STM32F3 part will need to define these two functions
* which are used to connect and disconnect the device from the USB bus. This
* is usually accomplished by enabling a pullup on the DP USB line. The pullup
* should be enabled by default so that the STM32 will enumerate correctly in
* DFU mode (which doesn't know how to enable the DP pullup, so it assumes that
* the pullup is always there).
