Hi every one,
presently i am working on STM32F407 USB, in my project i am configured STM as a host and MSC class as a device, but when i am connecting the pen drive (MSC class device), all interrupts are raised except host port interrupts.

what are the factors effecting for the host port detection in the STM32F407 Host, can any one please explain about this.

Thanks & Regards,
Chandu.Kurapati.
