I'm working on a ROG Zephyrus G14 GA402RK_GA402RK with Windows 10 and WSL and was trying your script diaotu.py but got the error message on the first write:
USBError: [Errno 5] Input/Output Error

Can you give me a hint how to fix the error?

I have never tried this (or any other libusb application) on WSL, I have no idea about how to use libusb in WSL, you may try native windows python and libusb

btw, I have returned my GA402RJ due to its poor quality, so I cannot debug this now

I've the same problem right now. I'm also trying to get this working on my GA402RK but in native windows and not in wsl and i'm getting the same error.
After setting PYUSB_DEBUG=debug and LIBUSB_DEBUG=4 the error log reported this line:
error [_hid_set_report] failed to write HID Output Report: [1] incorrect function

Sadly, i have still no idea what is causing this issue. @DTNGNR did you manage to fix it?
