Question

I want to get the unique id from an usb hard-drive with python for a project im working on. What is the easiest way of achieving this? Is there a better way to do it? Can this be done platform independent?

Answer 1

Use the system call to read in ‘lsusb’, and then parse the output.

import os  
cmd = 'lsusb'  
os.system(cmd)

Or an easier to parse solution would be the commands library.

import commands  
output = commands.getstatusoutput('lsusb')

And then you would manipulate or search output with regex for your device.
