info

Reports transport / popup status, not hardware data, and needs no device I/O of its own. Like every request method, the first call opens the popup and is answered only after the connection handshake completes — with no device connected yet, that means after the user picks and connects a device (bounded by a 60 s handshake timeout). Later calls in the same popup session are answered without device I/O once any request queued ahead of them settles (the connector sends one request at a time), and report ready: false / isAttached: false / transport: undefined if the device has since been disconnected.

Summary​

Whereas getDeviceInfo returns hardware device metadata, info reports the popup's transport state. On an unsupported browser the popup shows an error screen and the request ends with time_out.
