Because I have three PCI tuners and have three usb-to-serial connections
on them to control channel changing on the set top boxes I have, I put
some udev rules in place to create symlinks in /dev automatically.  Then
I reference the symlinks for the USB devices in mythtv for the channel
changing, and gone are the worries of what order things get identified
in. :)  Note that one of my set top boxes is connected via a true serial
port and didn't need a udev rule.

Anyhow, you could probably do something similar with your capture
devices to keep this problem from creeping up on you again with any
future upgrade.

[root at mythtv1 ~]# cat /etc/udev/rules.d/99-usb-serial.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001",
ATTRS{serial}=="ftE15H6A", SYMLINK+="X10"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001",
ATTRS{serial}=="ftDYP9O0", SYMLINK+="CID"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0557", ATTRS{idProduct}=="2008",
SYMLINK+="SD2"
SUBSYSTEM=="tty", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303",
SYMLINK+="SD3"

Not sure if this will help, but since I find that mythbackend does still
periodically exit on its own, I don't bother with the systemd (or the
older init.d) service startup since they can't auto restart it yet.  I
start it manually at system boot via a crude wrapper script.  Note that
"mythtv1" is my dedicated backend host.. I could have probably just
checked to see if mythbackend existed, but it does the work.

[root at mythtv1 bin]# more mythwrapper.sh
#!/bin/sh

if [ "$(hostname)" == "mythtv1" ]; then
   if [ ! "$(pidof mythbackend)" ]
   then
       while true; do
#              cd /var/log/mythtv; /usr/bin/rm -rf *
          /usr/bin/mythbackend --logpath /var/log/mythtv/ --pidfile
/var/run/mythbackend.pid > /var/log/mythtv/mythbackend_
master.log 2>&1
       done
   else
           echo "Mythbackend is already started."
  
   fi
  
fi
if [ ! "$(hostname)" != "mythtv1" ]; then
   if [ ! "$(pidof irexec)" ]
   then
           echo "Irexec is not started. Starting Irexec..."
           /usr/bin/irexec > /dev/null 2>&1 &
   else
           echo "Irexec is already started."
   fi
  
   if [ ! "$(pidof mythfrontend)" ]
   then
       while true; do
       /usr/bin/mythfrontend > /local/mythtv/mythfrontend.log 2>&1
       done
   else
           echo "Mythfrontend is already started."
  
   fi
