To write into endpoint 0, you'll need the device.ctrl_transfer(bmRequestType, bmRequest, wValue, wIndex, packet) instead of endpoint.write(packet).

The bmRequestType, bmRequest, wValue and wIndex correspond to the same elements in the USB control request. The fact that the Windows software uses hidapi suggests the control transfers are done according to the USB HID specification.

This answer here on Stack Overflow describes how to make USB HID set/get operations on plain PyUSB.

But since the source code you're porting uses hidapi, using the Python hidapi interface might make the process more straightforward. This question has an example of using hidapi in Python, and the answers also talk about alternatives.

Python seems unable to find hid library on Mac

Asked 2021-Nov-15 at 21:12

When I set up a python virtual environment and install the hid module it doesn't seem able to find a library that I've installed with MacPorts. I'm running Mac OS Big Sur 11.6.1 and I've also installed python with MacPorts. Any troubleshooting ideas?

ANSWER

Answered 2021-Nov-15 at 03:48

So your problem in fact isn't that your python can't find the hid package.

When importing hid, hid tries to load native libraries that are not installed. this can be solved (on MacOS) using brew install hidapi as described here

Here is a minimum code example that seems to work. The HID device is a Teensy board that uses its RAWHID.recv() and RAWHID.send() to exchange text and binary with the host computer.

You must link your program with Hid.lib.

Go to project settings / linker and add it to all targets.

The solution was to use udev rules. These rules worked in my case.

I also end up using a different Python library https://github.com/apmorton/pyhidapi. But I am sure the original cython-hidapi would be as fine.

You must install libusb-1.0 on your system. You seem to be using Homebrew, so you also have to install it specifically via Homebrew, because that's where pkg-config is looking for it.

It's possible that Homebrew doesn't offer this library under this exact name, or that the hidapi crate isn't compatible with macOS. Check the hidapi crate for details, as it's a crate-specific problem.
