idevicedebug (part of libimobiledevice) is running from terminal, but not from code!

Hi,

When I'm running the following command from my Mac OS-X 10.11.5 terminal window its working and launching the application on the ios device connected to my computer via USB:

idevicedebug run <installed app>

But When I try to run it from inside python code (using subprocess library) I'm getting:

OSError: [Errno 2] No such file or directory

Or (if shell=True is enabled):

run: idevicedebug: command not found

def run_command(command):

    args = shlex.split(command)
    p = subprocess.call(args, shell=True) #False

the idevicedebug is installed properly and found under /usr/local/bin:

$ locate idevicedebug
/usr/local/Cellar/libimobiledevice/1.2.0/bin/idevicedebug
/usr/local/Cellar/libimobiledevice/1.2.0/bin/idevicedebugserverproxy
/usr/local/Cellar/libimobiledevice/1.2.0/share/man/man1/idevicedebug.1
/usr/local/Cellar/libimobiledevice/1.2.0/share/man/man1/idevicedebugserverproxy.1
/usr/local/bin/idevicedebug
/usr/local/bin/idevicedebugserverproxy
/usr/local/share/man/man1/idevicedebug.1
/usr/local/share/man/man1/idevicedebugserverproxy.1

Note:

If I run other system commands (like: ls -l) its working from code, xcrun command is working as well,

The issue is with libimobiledevice commands!

B.R.
