WebAs USB is a packetized interface, you could also have an unsuitable algorithm in the firmware for deciding when it's worthwhile to send a packet. Finally, while the CDC-ACM driver should be vendor independent, the posix serial API by which application programs access it can be configured to a wide variety of behavior. WebMar 4, 2024 · USB CDC examples do not handle modulo 64-byte transfers correctly ZLP packet is not sent automatically because the driver does not know if the user data transmitting is done. Here is a fix proposal by using CDCSerial to transfer data.
