What it does:
Uses hidapi (pip install hidapi) to:
Enumerate devices with VID/PID 0x2886:0x001a (Seeed / XVF3800).
Open the first matching HID interface (or a specific --path).
Read reports in a loop and print them as timestamps + hex blobs.
You (or testers) run it, press/release the XVF mute button a few times, and paste the output into the Discussion so we can see which byte/bit is the mute state.
