[Tutor] connecting to USB

[BILAL Mustapha]

Hello,

  I am working to connect to a serial link (USB). In order to do that I 
have to write this command:

sudo ../../tools/stm32w/serialdump-linux -b115200 -d10000 (keeping in 
mind dat*serialdump-linux*, which is in the path, is not a folder, it's 
an executable)

To get to the root, I have used: returncode = 
subprocess.call(["/usr/bin/sudo", "/usr/bin/id"])

Then to connect to the USB through the command above I tried the following:

usb = 
Popen(['../../tools/stm32w/serialdump-linux','-b115200','-d10000'], 
stdout=PIPE, stdin=PIPE, stderr=STDOUT)

usb.communicate()[0]

  But I am getting an error, it's considering that serialdump-linux as a 
folder!!

  Any help how I can run the command?

  Many thanks
