USB/Startup Problem with the new STM32F429 [V2]

my problem should be simple to solve, but due to it's rather undocumented nature I resort on posting it to this forum. 

When plugging in the STM32F429 board into a pc, it gets detected as flashdrive with around 2 MB space and two files on it (MBED.HTM and DETAILS.TXT). I want to avoid that.

Especially because that "opening folder" sequence is directly linked to the bootup sequence. That means, if I power the STM32F429 by battery or usb-charger, it's not booting until the folder can open up.

I couldn't find any documentation on that issue. It only appears on the new STM32F429 Disco boards.

Please Help!
