To get the same output for windows, you need to set them as environment variables: ``` set LIBUSB_DEBUG=4 set PYUSB_DEBUG=debug python your_code.py ``` (I think that's the right way for...

Hi @stepandr47 hmm, I was hoping we'd see that the libusb version would differ between the two. As it is, it is probably a bit hard to compare. (the linux...

Hi @stepandr47 Thanks for the clean debug logs ❤️ I asked for advice on how to best proceed with the debugging at pyusb/pyusb#390 I'm sure they'll be able to help.

So, new things to test: - [x] create debug log on a different linux DISTRIBUTION compared to the one you used. (are you running the same distro on both the...

You need to follow: https://python-seabreeze.readthedocs.io/en/latest/install.html#step-1-linux probably you're missing: `sudo apt-get install git-all build-essential libusb-dev`

Just a quick question: do you connect the spectrometer through a USB hub on the PI? Just looking at the packet captures it seems the VM communicates through a USB...

So just to be clear, the three test systems are: 1. Windows Host --- Spectrometer connected directly to Host PC 2. Windows Host running Ubuntu VM --- Spectrometer directly connected...

Okay, so the packet capture was not conclusive. https://github.com/pyusb/pyusb/issues/390#issuecomment-928607736 I guess we continue the Quest and our next stop is the linux-usb mailing list. :crossed_swords: :european_castle: :dragon: In the meantime...

Hi @juliowissing yes, python-seabreeze returns the raw readings, and has support for dark_count and nonlinearity correction. What are you referring to specifically when you mention `sensitivity calibration`? Did you store...
