to get the output you can use

output=subprocess.check_output(["echo", "Hello World!"])
print output
# Hello World!

How about write the result to a file and read this file in python?

subprocess.call("RPiHubCMDTool.exe dev > result.txt", shell=True)
f = open('result.txt', 'r')
# do something with f
