Product ID and Vendor ID used only supports single HID device

[alijani1]

Where did you manage to get this VID and PID as it seems its the only one i can get C64 Mini to see the device. Were you able to get any other VID/PIDs to work? please share if any.

The problem with the ones you used is they dont work with my devices that have multiple HIDs and it makes linux only see one HID device even though there are multiple HID and report IDs on the devices I created.

Do you mean for these values?
*.build.vid=0x22BA *.build.pid=0x1020
I guess it is from C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt
*.build.usb_product="C64Mini Arcade to USB converter"

Maybe this could help https://thec64community.online/thread/763/using-multi-joystick-adapters-trouble
Like vid="0x8282" pid="0x3201".
