I want to programme a USB host CDC. This works as far as it goes. This means I can receive and send data. My problem is that the receive interrupt is called 2 times for data packets with 64 bytes.It is also always called once too often for packets >6...
Rarely, USB does not work properly, and in parallel with USB malfunction, there are problems with data integration on the USART1 channel.
The above problems occur only with SOF packages with voltage distortion on USB lines: see oscillations on "USB signal with SOF" vs "USB signal with no SOF" when there is no oscillation and no problems indicated.USBOscillations occur on SOF packages, ...
