Windows Utilities Incomplete

[fragmuffin]

Importing upytester in windows raises:

upytester/src/upytester/pyboard/utils/utils_win32.py

Line 7 in 2027cf2

raise NotImplementedError("Windows not supported, yet")

Why?
Because I don't know how to do the following in windows reliably:

• list all connected pyboards by serial number
• map a given serial number to:
  • serial port device (eg: COM2)
  • mountpoing (eg: D:\)
• mount / unmount (aka: safely disconnect mass storage device)

I'm a Linux guy by nature, so I attempted to do this for a few days back when I had a windows machine for work, but didn't succeed.

The contents of utils_win32.py is mostly experimental... some of it works, but not reliably.

Solution?
I don't know, but I'm open to ideas.
I'm open to the idea of implementing it in a more suitable language, and using system calls to invoke a builtin binary... but ideally the solution would be pure python, or compiled with python hooks.

workaround is implemented and documented in PR #3 (not a fix)

Potential solution in pyusb lib:

python -m pip install pyusb
