The main purpose of WebUSB (as far as I can see) is to enable certain CDC (in particular - but not limited to) devices communicate directly with browsers visiting certain trusted sites (listed inside a binary object store - sent on initial handshake). The spec is here: https://wicg.github.io/webusb/ (already running fine in chrome stable) Examples: https://www.youtube.com/watch?v=Z1Nk2hH2wFE https://www.youtube.com/watch?v=o7wGt9RfHVA https://twitter.com/denladeside/status/817451203076427783 I'm guessing the solution will consist of 2 parts: 1. make sure no WebUSB device is picked up by modemmanager (modemmanager task) 2. make sure that webusb devices will be somehow accessible to be used by a browser running with user permissions (current temp solution listed here: adding user to plugdev, adding 0664 permissions to device: https://developers.google.com/web/updates/2016/03/access-usb-devices-on-the-web ) (udev/systemd task). For 2. we need to either making all webusb devices accessible or find some other way the browsers can - in a generic way - gain access. In all cases, it's important that no USB interfaces has been pre-claimed by the system (e.g. by cdc_acm) or it should be possible for the browser to throw off the claims. thoughts? br Lars
