I have successfully run the ThreadX+USBX program on the H7 chip. The USB composite device (CDC ACM+HID) is used, so I tried to implement the same function on F105RBT6, but I ran into trouble, running USB on F105 The composite device can run normally at the beginning, but after 30s, the USB will be disconnected and reconnected, and the USB will not be recognized. I learned that H7 has 9 endpoints and F1 has only 4 USB endpoints. Will it? Is USB working abnormally because of the number of endpoints?
