Hi!
Using STM32F105 microcontroller.
I've created a clear USB CDC project with STM32CubeMX (5.0.1).
It works well when connected to Windows 7 host machine, Virtual com port is appearing on Device Manager.
But when i connect to macbook I've got "HS01@14100000: AppleUSBHostPort::disconnect: persistent enumeration failures" in dmesg output (command: "sudo dmesg | grep enum").
Using oscilloscope, I see several activitys on usb lines during about 5 seconds after device connected and then constant levels.
Help, please!
