Hi,
I am presently working on STM32F407 USB, for my understanding i am referring the RM0090 Reference manual.

In that manual for USB OTG FS, Global interrput register (GINTSTS) 29 bit as DISCINT bit at there they given as it is accessible only in host mode.for raising that interrupt we have to mask that interrupt that is  in GINTMSK register 29 bit they given that DISCINT Masked only for device mode.

my problem when i am disconnecting the device from my host port,disconnect interrupt must be raised but that is not happening there is no response from the core.please explain me why it is happening like that and there is any problem in reference manual.
 
Thanks & regards,
Chandu.Kurapati.
