USB Global Interrupt status reset value

Hi, The NS9750 USB doku says that the reset value of the Global Interrupt Status register 0x90100010 is 0, but this is incorrect. After Power-UP its 0xa1f when a USB memory stick is plugged and 0x810 when nothing is plugged, and after pressing the reset button its 0x200 in all cases (Tested with the development Board, and with our own board with flash disabled).
