Stop bootloader mode on USB connection

[andrey]

I'm using vanilla version of the dfu_dual_bank_ble_s110 project on top of my application. The problem is that the firmware enters bootloader mode whenever a USB is connected to the board (pca10028/pca10031).

How do I stop that from happening?

@andrey: When you mentioned "a USB connected to the board" was there any other power source ?

Do you have application flashed on your board ? If you don't have, whenever you power on the board it will stay in bootloader mode.
