to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1890365 Title: [snap] Web Serial fails to access local device Status in chromium-browser package in Ubuntu: Incomplete Bug description: A javascript-based web page works fine when accessed through Chrome, fails to recognize that any devices exist when accessed from Chromium on the same Unubtu 20.04 platform. The code includes the following snippet: const requestOptions = { filters: [{ usbVendorId: 0x1881 }] }; port = await navigator.serial.requestPort(requestOptions); await port.open({ baudrate: 9600 }); writer = port.writable.getWriter(); reader = port.readable.getReader(); Under Chrome 84.0.4147.105 (Official Build) (64-bit), ttyACM0 device is listed in the pop-up, is selectable, and can communicate. Under Chromium 84.0.4147.105 (Official Build) snap (64-bit), the pop-up contains only "No compatible devices found" message. Experimental Web Features flag is enabled in both browsers.
