add the following lines in /etc/rc.local could wake up the touch screen, it works every time after booting up.
Or, you can run it manually to check if the commands work.

sudo rmmod hid_multitouch ; sudo modprobe hid-multitouch ; find /sys/bus/usb/devices/2-3 -name control | xargs -I '{}' sudo sh -c "echo on > '{}'"
sudo rmmod hid_multitouch ; sudo modprobe hid-multitouch ; find /sys/bus/usb/devices/2-3 -name control | xargs -I '{}' sudo sh -c "echo on > '{}'"
sudo rmmod hid_multitouch ; sudo modprobe hid-multitouch ; find /sys/bus/usb/devices/2-3 -name control | xargs -I '{}' sudo sh -c "echo on > '{}'"

My touchscreen is linked to /sys/bus/usb/devices/2-3, check the idProduct and idVendor in that directory to make sure which directory your touchscreen is using.
