Nice project. I’m also trying to access the spyder sensor using python with libusb via ctypes. I don’t understand anything about the measurement values (80 bytes/color???) sending by the sensor. My only success is to be able to send the 0xc6 and 0xc7 requests (at the beginning of the USB Log). Thank you for your USB Logs because there are more details than mine which are delivered by Snoopy.

I have managed to communicate with the device (more or less) and have gotten expected replies until packet 1789, right before the measurements start.
