No, the first line should be (uncommented):
SUBSYSTEM!="usb_device", ACTION!="add", GOTO="hiptop_rules_end"

$ groups jack
This is just to make sure you don't forget your groups if something goes

# groupadd hiptopusers
Creates the group
# usermod -a -G hiptopusers jack
Adds jack to the hiptopusers group
Then, restart the computer.
Let me know how it goes.
