I am writing to you because I have a problem with my chipwisperer which I just received a few days ago.
I can’t connect to it. I’m using the virtual machine in virtual box (the last version) and last realses (here Releases · newaetech/chipwhisperer · GitHub) in windows 10
i make this test in 3 differents pc and always this same error when i want to connect :

if i scan usb with usb-devices, i have this info :

Do you have any idea what I could do?
Thank you.
