I use stm32_vcp_1.3.1 application for setting USB FS. I use it to send data to APP on the Win. It work fine but when the APP crush unexpected and the USB port stay open I don't get any announce for it (I have announce on port close or disconnect only) and after some time i see that I stack in the USB interrupt loop " OTG_FS_IRQHandler " when it specifice get flags for TxFiFO and SOF.
I can't get out of this loop and couldn't get to my main nether cut this loop or set and announce about it.
Is there a way or a function I can use to fine this scenario happened?
