Hi!

Attempting to establish connections with 2 USB devices from the same web application,
I manage to link to only one device, while encountering an error for the second:
'A Javascript error occurred in the main process
Uncaught Exception:
TypeError: One-time callback was called more then once as Session: at Session -path to index.js file'.
I am curious whether the WebUSB standard facilitates connections to multiple USB devices within a single web application.

I have tried to use Electron to achieve this. My web app is loaded into Electron Chromium window.

I don't recognize this error as one generated by the Chromium WebUSB implementation. WebUSB supports connecting to as many devices as the user has granted permission to access. This looks like it might be an application error.
