#CDC ACM DRIVER LINUX HOW TO#

But how to identify the root cause and get it fixed. However, in some cases, we can not change too much in OS. It seems both firmware and OS have issues.

I have tried different tools, including gtkterm/echo/cat/stty/minicom/usbmon, python serial and lua.io.

Maple STM32F103 USB driver (to be tested)ДЄnd firmware #1 doesn't work for #1/2/3 OS, while some other hardware may work with most of the OS.

STM32F103C8T6_USBSerial from mbed community.

I have tested the following boards/firmware: However I find the same device/firmware are not working well in all Linux OS. Due to development of IoT, I need a stable USB CDC ACM firmware in certain microcontroller.
