reset USB device when resume/wakeup my desktop with linux mint 17 (ubuntu 14.04)

Cause I've replace my desktop before, from Homebuilt computer that old than 8-year
To brix mini computer, and I've solve the monitor VH226H HDMI source could not sleep issue by replace it to VGA source...

Now I have a computer that can sleep/hibernation and wakeup/resume
but following issue is, I've plug a DVB-T usb dongle on my Desktop, and I'm using Me-TV 1.4 as my TV player,
Me-TV 1.4 turn into server and client architecture, so server application will stay in background, keep open device

If computer sleep or hibernation, it wake up or resume quickly, but DVB-T dongle might be work abnormal, maybe the driver does not implement relative power management function? I don't know:~

I need replug my DVB-T dongle , kill Me-TV server manually to make it work
Hm.... Try to make it easier:)

put following code to /usr/lib/pm-utils/sleep.d, save as 99ZZ_my_script, and make it executable
it could kill me-tv both server and client when sleep,
and when you wake up, find the usb port number, force it reset

#!/bin/sh
# resume me-tv-client if exist

case "$1" in
 hibernate|suspend)
  #echo "7 blink" >/proc/acpi/ibm/led
  killall me-tv-server
  killall me-tv-client
  ;;
 thaw|resume)
                for X in /sys/bus/usb/devices/*; do
                    #if [ "$VID" == "$(cat $X/idVendor 2>/dev/null)" -a "$PID" == "$(cat $X/idProduct 2>/dev/null)" ]
                    if [ "MDTV Receiver" = "$(cat $X/product 2>/dev/null)" ]
                    then
                        Port_Number=`echo $X | awk -F / '{print $NF}'`
                        #echo "Found $Port_Number"
   echo $Port_Number > /sys/bus/usb/drivers/usb/unbind
   sleep 1
   echo $Port_Number > /sys/bus/usb/drivers/usb/bind
                        break
                    fi
                done
  ;;
 *) exit $NA
  ;;
esac

exit 0
