USB ISTAT register

Hi, I seem to be having a problem clearing the flags in this register... I have read in the datasheet that they are cleared by writing a 1 to the bit, which is counter intuitive but nevermind, but when I do write a 1 (or a 0 for that matter) the register doesn't change, it appears to be read only.


I have tried to use several USB example projects (every one I could find), and none of them work, potentially because of this problem, they all rely on the flags being cleared and thus end up getting stuck in infinite loops etc.


Any ideas?
