Canon LBP3300 usb port keeps on changing

Question

Following the guide https://wiki.archlinux.org/index.php/Canon_LBP2900 , I have LBP3300 worked fine.
However I get 2 problems
1. After a some kernel upgrades (which is relatively often in Arch Linux) the port keeps on changing (/dev/usb/lp0, /dev/usb/lp1) which make udev rules did not work properly.
2. "/etc/rc.d/ccpd restart" does not work properly
So I write this scripts /home/share/bin/cannon-lbp3300-starter
#!/bin/bash
## restart the cannon lbp3300 properly
if [ $UID != 0 ]; then
echo "This command should be run as root!"
echo "Example, in /etc/udev/rules.d/85-canon-capt.rules:"
echo 'KERNEL=="lp*", SUBSYSTEMS=="usb", ACTION=="add", SYSFS{idVendor}=="04a9", RUN+="/bin/bash /home/share/bin/cannon-lbp3300-starter"'
echo 'KERNEL=="lp*", SUBSYSTEMS=="usb", ACTION=="remove", RUN+="/bin/bash /etc/rc.d/ccpd stop"'
exit 1
fi
## find the USB device
USBPORT=$(echo /dev/usb/lp* | head -n 1)
## exit if port not found
if [ x$USBPORT == x ]; then
echo "USB port not found!"
exit 1
fi
## everything looks fine
## name of the printer device (should be correctly setup in cups)
PRTNAME=LBP3300
## set the PATH
PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/bin
## stop the cups
/etc/rc.d/cups stop
## stop the ccpd completely
/etc/rc.d/ccpd stop
killall ccpd
killall -9 ccpd
## start the cups backend again
/etc/rc.d/cups start
## clear printer queue
lprm -PLBP3300 -
## remake the cannon printer
ccpdadmin -x $PRTNAME
rm /var/ccpd/fifo0
mkfifo /var/ccpd/fifo0
chown lp:lp /var/ccpd/fifo0
ccpdadmin -p $PRTNAME -o $USBPORT
## start the ccp backend again
/etc/rc.d/ccpd start
## done. hopely things are really OK now

I also have this problem with my brand new Sony Xperia Z3 Compact :/
- The unit is almost only 2 weeks old, but I have just been in the store where I did buy it, and have now being told that it is being sent to Sony to get fixed. So hopefully then I get it back, I don't see this problem anymore
I do however think, that Sony should try to look into this problem, so no customers will get a faillure in their devices anymore, as being described. I have just been unlucky in this accidentally problem. Besides that, I'am very happy for this top modern Android phone from Sony. Keep up the good work Sony!
