Posted on February 16, 2018 at 17:10I am developing on the STM32F0 using the USB library and encounter problems when my main routine starts to send data early after the device received the SetConfiguration request.
So far I could narrow it down to the USB stack failing to properly transmit descriptors when I send a data packet directly after getting configured. Data sending is handled from the main loop, so no exception is active at that time.
Could it be that there is a problem if a USB event comes in while the library is loading my endpoint for data transmission?
And would the USB stack work if I disable interrupts before calling it?
