| * 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). |
