I am trying to connect to an ANT+ usb stick using Web Serial API in Google Chrome. On linux (Ubuntu) it works out of the box, but on MacOS (v12.1) the device doesn’t show up into the search box. It does show up when using the web-serial-polyfill, but it is unfinished and missing features, and since the navigator.serial is present I wish to avoid using the polyfill.

var port = await navigator.serial.requestPort({ filters: [{ usbVendorId: 4047 }]});

Gets me ‘No compatible device found’. Requesting without params shows other devices, but not the ANT+ stick.

Any ideas why is that?
