Once Windows detects a HID device as implementing a more specific API in the WinRT set, it seems to hide it from the generic WinRT HID API. While you can often still list the device, I couldn't actually open it or send messages.

This is mostly an issue for the lamp-array subcommand, which is a direct binding to the Lighting and Illuminate HID API.

I haven't tried yet, but I suspect the lower-level win32 HID API might allow access to this device, even if the higher-level APIs do not: https://learn.microsoft.com/en-us/windows/win32/api/_hid/
