Do you also have the other driver installed that I gave you for your Aqara H2 US? If yes, this driver is picked first and it doesn’t include the necessary profiles for your keyboard.
I can also check if I have to add your device’s VID/PID to the driver, but I don’t really think so, because the EP discovery should happen anyway.
I’m back home at the computer in about five hours… Maybe my german-hating, always tired stalker shows up in the meantime and helps you out - he’s a “developer”, the “de facto boss” after all.
