[chirp_users] Chirp not identifying Kenwood TM-V71

Thanks for the suggestions. Evidently with the V71 as first choice I was
fooled into thinking
that Chirp was conversing with the radio.

I think the problem may be something called "modem-manager".

I checked Menu #519 "PC terminal baud rate speed" and found that it was
9600 baud.
The manual indicates that this is default and I found this to be the case.
I also checked that the interface cable is securely mated with the
microphone jack.

I checked the /var/log/syslog file on Ubuntu and found that after
connecting the USB device
the "modem-manager" was opening and closing the USB0 port. This is
something I had
not heard of before. It was not immediately clear how to terminate this, if
the process was
killed it was respawned.

I hoped that this was a feature (mis-feature?) on Ubuntu so switched to a
laptop with RHEL 6.2.
One again, after plugging in the USB connector I found that modem-manager
was fussing with the port.
Could this be getting in the way somehow? I see the same behavior in which
radio is not detected.

Here is the /var/log/messages from the RHEL 6.2 system:

I tried the USB cable for the Wouxon hand held radio and was able to
download from that radio.
Here is the /var/log/messages file. Note that no mention of "modem-manager".

What do you think? Is modem-manager involved in the problem or is it
something else?
Has the Kenwood USB cable been used with Linux and a V71?
Other suggestions welcomed.
