Yes, I already tried that: I used the device in Windows and I sniffed all
USB packets that were sent. And everything was the same as I am trying with
my python code, and also the same that is written in the communication
specifications that the manufacturer gave me.
I have contacted the manufacturer, hopefully they will answer me soon (I
will let you know if I find out anything important). But I don't understand
how it is possible that the device works with its Windows software and it
doesn't when I try to send exactly the same with pyusb in Ubuntu.
Once again, thank you for your time and your ideas!
