Each copy of Analog_Bridge can only use one Vocoder. So, for USB1 you will have a second copy of Analog_Bridge.
These lines are meaningless and should be gone.

I thought they were removed in the current version of AB. I suggest a apt-get update and a apt-get upgrade.

The line I'm most concerned about is:
M: 2018-07-24 18:24:22.631 DV3000 latency is currently set to 16

You want this at 1.
echo 1 > /sys/bus/usb-serial/devices/ttyUSB0/latency_timer

Verify it is now at 1:
cat /sys/bus/usb-serial/devices/ttyUSB0/latency_timer

I am building DV switch on the same box where I was experimenting with XLX - so the device was already there.  Initially I got some audio to pass from DMR to analog and it sounded kind of "muddy" so I thought I would give the hardware a try.  I may want DSTAR in this too so I would have some hardware transcoding in any case.

I unplugged the 6 channel device and plugged in two ThumDV's. They appear as /dev/ttyUSB0 and /dev/ttyUSB1.
I modified the ini file and have this startup (below) -
