there is a switch on the back to choose between "game" and "demo". Demo puts it into an attract mode i'm showing here.

this really shouldn't be emulated. unless you actually have the physical device it loses all of it's purpose in trying to simulate an a more authentic slot machine feel. i'm okay with this being given a won't fix label and closed.

Please try to find which command controls each LED using the following script. You'll need to update the path to libusb-1.0.dll and to load the WinUSB driver with Zadig.

leds.py

I don’t have the device anymore. I needed to sell it for money and space before my baby was born.

Fun fact: wTotalLength is wrongly configured 😂. For 1x config + 1x interface + 1x ep it should be 9+9+7=25. The difference of 9 is likely a missing HID descriptor they have removed after copy-pasting the config descriptor from a different device, without fixing wTotalLength 😂. As result, the request overflows and returns the first string: ** UNRECOGNIZED: 04 03 09 04. What a mess
