Consider using libusb instead of running commands

[jomo]

libusb works basically everywhere and provides a single interface to list and interact with usb devices.

Thanks for the issue. Will look at this when I'm not as swamped!

This doesn't seem to work on Windows. I can't get pyusb to work without having to install the driver manually, and pip install libusb doesn't help either. If we can't pull in everything needed with Python dependencies, then that's a hard stop.

@jomo What do you think about what @GhostofGoes said? To me this looks like a no go if the driver has to be manually installed.

@GhostofGoes did your try pip install libusb1?

libusb is a lib written in C with Haiku in C++. https://github.com/libusb/libusb

libusb1 is a python module for libusb and can be found via the following urls:

According to this, windows is supported https://pypi.org/project/libusb1/1.6.4/#supported-oses

Installation https://pypi.org/project/libusb1/1.6.4/#installation

@jomo I think you have a great idea.

[GhostofGoes]

No, I wasn't aware of libusb1. I'll give it a try in a day or two once I'm on a Windows box.

It installed fine into a virtual environment with pip install libusb1. However, it failed to import due to an issue loading a DLL. Full traceback below:

As I said before, we want something that is able to be installed via pip with no any extra dependencies, like requiring the user to separately download and install a library or other package.

What with Windows not being an issue anymore, this issue and #58 need to be consolidated.

This is fixed in the new branch
