推荐答案

我的方法并不完美，但目前对我来说是一个很好的解决方案，仅供大家参考.通过WDK(Windows Dev ... Kit)中的devcon.exe，以及我的代码如下.

My way is not perfect, but that is good solution so far for me, just for you reference. Through the devcon.exe which is in WDK(Windows Dev... Kit), and my code as below.

try:
    output = subprocess.Popen(["devcon","status","*"], stdout=subprocess.PIPE, stderr=subprocess.PIPE)    #useing comma "," not space " " in Popen[]. replace the key word "*" to what you want to search.
    stdout, stderr = output.communicate()
    print "output: \n", output
    print "stdout: \n", stdout  # output here if ok. 
    print "stderr: \n", stderr  # output if no arg     
except subprocess.CalledProcessError:
    print('Exception handled')
