I am using the STM32F207 for a High Speed USB custom HID application. The USB device library for the STM32F2 does not have Interrupt OUT feature in HID, which I have now added.
My problem is that when I send some data from the PC to the board, the USB core does not generate any interrupt, and the execution never reaches my INT OUT endpoint callback function. The USBlyzer software shows data being transmitted from PC to the device. But it does generate an interrupt when I send data from device to PC using INT IN endpoint.
I saw in the initializations that interrupts have been enabled for both OUT and IN endpoints. So I dont know where I am going wrong. I am using external high speed PHY.
Any help would be highly appreciated.
