I have the STM32L152C discovery board.  I used stm32cubemx to create a very simple bare bones project which will essentially allow me to try out the DFU mode with the PA11 and PA12 pins and a usb cable.  I am not getting any indication that my board is being detected by my computer(s).  I have the boot0 pin connected to Vcc, usb green wire connected to pin PA12, usb white wire connected to PA11, usb red wire connected to ext_5v and usb black wire connected to GND???


What am I missing?
