We are working on radio dongle application using STM32F411/13. We have mostly everything working, except for a lingering issue with USB. Details of the issue are as below:
We also tried different ways of reproducing this issue, and the easiest way to do so was by closing the host application while the communication between USB host and device is ongoing. So, if i abruptly close the host application and if the OTGFS device happens to have started the IN transfer it ends up in this scenario where IN transfer complete interrupt never fires.
Next, if i try to reopen the host application it does not work and OTG FS device is stuck in this state until we do a power cycle. I do not observe this issue with a different hardware platform that we have (not based on STM32 MCU).
Can someone please share some insights here as to how to overcome this problem. Your help is much appreciated.
