Not really:
PC->V71: ID
The V71 in this case is printed by the Python object - it hasn't yet
talked to the radio, it's just saying "I am a Python V71 radio interface
object". You'd see the same thing if the radio were an Icom and you told
Chirp to look for a Kenwood - Chirp would create a Kenwood object, talk
to the Icom, and the object would then report back to the program "Dunno
what this is, it isn't a Kenwood."

"What we have here is a FAILURE to COMMUNICATE."

It looks like the radio isn't responding. Silly things to check:
1) are you sure you are selecting the correct serial device - it should
be /dev/ttyUSB[0-3] - you can run dmesg after you plug the cable into
the computer to see what name got assigned to it.
2) Is the cable fully plugged in? I know getting the cable all the way
into my TM-V7 is a pain.
