I loaded the latest CircuitPython to my Feather M0.
Basically / Initially everything seems to work fine...
However, often in Putty (connected to the board) transmission stops and Putty comes back with a error message, saying he can not write,,,
Mentioning some strange semaphore problems.
Never had this problem with other MicroPython boards like (Huzza 8266 / Huzza32 which I also use),
Any Ideas?
It seems to be a Window USB serial driver issue. (I am using Win10 64bit).

Re: Feather M0, CircuitPython, REPL problem
Which versions of CircuitPython and Putty are you using?
Windows 10 contains a built-in driver (usbser.sys) that should be installed automatically when you first plug in your Feather M0. It's possible there's a third-party driver that's interfering somehow. Look at the "Ports" section in Device Manager and check what appears when you plug in the board.
Could you tell us the details of the Putty error?
Also try another USB cable and/or port, in case there's something flaky.
