Powering STM32F4-Discovery from micro usb

I'm looking to power the STM32F4 discovery from the micro usb port, while keeping modifications to the board at a minimum (I don't have great faith in my smd soldering).

This is my current idea:
- remove r46 to ensure that the usb regulator isn't turned on by accident. 
- connect a diode from the PA9 pin on p2 to one of the 5V pins

Am I going to run into any problems with this setup?
