Here, I’ll chip in some words of my experience of UPA USB original and the clone (green & red board).
I test in various china UPA interfaces and the interface that not block and dont need any modding and any eeprom is red one.
I test in 2 red UPA with 22.214.171.124 (software from china)and works perfect. The only thing to bypass the reg is run soft and then connect UPA to USB and when ask for registration not write nothing, only click accept and run ok.
This days i make a how to. its simply.
1º install soft.
2ºcopy 3 files overwritten old.(this is the software from china its in all pages).
3º run soft.(it will run without asking nothing).
4º plug UPA(when UPA is plugged a window appear and ask for registration, in this moment click in activate).
I make a step that is use the new drivers whit UPA(in chineese pages are how to install and is what is the correct driver) but whit old drivers works too.
I make this steps in 2 red ones and works ok. but if try on a green PCB the soft kill the 24c128(if i remember well) and must be reprogramed.
The only difference between red and green is a pic that in red isn’t in mainboard and has in USB board. i think in there is any serial.
Also, I help collect reviews of UPA-USB device programmer… look here

Its ok but to have the clone if buy original then you will happy with it
