Python cannot access my usb device - insufficient permission - python-3.x

Question

Python script cannot send print to my usb Epson receipt printer
I am new to Ubuntu. I am trying to send some text to a thermal label printer connected to my computer via usb. Upon executing the code in Visual Studio Code by pressing the F5 key, I get the below error
File "/home/hdadmin/Documents/Python/POS/env/lib/python3.6/site-packages/usb/backend/libusb1.py", line 595, in _check
raise USBError(_strerror(ret), ret, _libusb_errno[ret])
usb.core.USBError: [Errno 13] Access denied (insufficient permissions)
However, if I execute the same code with:
sudo python3 -m test5.py
then, it prints out all right. I have done many google searches, and it seems that this is a problem related to my rule settings, so I made the following rule in /etc/udev/rules.d/printerRule.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="1208", ATTRS{idProduct}=="3605", MODE="0666", OWNER="hdadmin"
Still the problem persists.
The reason why I need to solve this problem is, I later need to compile the Python script using pyinstaller. If I compile as it is right now with
pyinstaller --onefile test5.py
The compile process will be fine, but I will still not be allowed to use the usb device when running the compiled file. Below is the full error report

usb.core.USBError: [Errno 13] Access denied (insufficient permissions)
Since I am new to Linux and Ubuntu, I need help and advices so that I can get permission to the usb devices connected to my computer. The expected outcome is, I should be able to run the test5.py by without the need for
sudo python3 -m test5.py

Thanks to gst. You are fully right. My mistake is during my .rule creation
SUBSYSTEM=="usb", ATTRS{idVendor}=="1208", ATTRS{idProduct}=="3605", MODE="0666", OWNER="hdadmin"
Instead it should look as below, where GROUP="users". I misread the "users" and substituted it with the user name. I changed my rule to as below:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1fc9", ATTRS{idProduct}=="2016", GROUP="users", MODE="0666"
and then in termial write
$ sudo udevadm control --reload
and restarted the computer.
