Rokid

USB glasses whose state arrives unsolicited: the periodic state packet carries brightness, volume, key state and all three sensor axes.

Models and how they are reached

Model	USB id	Protocol	Check it
Air	04D2:162F	rokid	Device check
Max	04D2:162D	rokid	Device check

What we can read from it

• Read brightness, volume, key mask, proximity and sensor axes by listening — no command is sent
• Estimate the panel's own cadence from its vsync timestamp

What we cannot, and why

• The serial number travels over a vendor control transfer, which WebHID cannot issue; that single value is unreachable from a browser.
• This model publishes no display-mode field, so the mode check is skipped with the reason shown.

Academy articles are the closest thing to a manual, including the firmware update walkthrough.

Still stuck?

The walkthroughs ask what you see and then name the layer at fault — cable, settings, firmware, device, content or host: no 3D · no sound · ghosting · not detected.

If your device reports a USB id that is not in this table, that is useful to us: run the device check and note the vendor and product id it prints — models are added from exactly that evidence, not from press releases.
