I would recommend you use Trezor Suite.  It's an easy to use app, has a lot of features, is compatible with multiple currencies, and it should connect to your Trezor One without the Trezor Bridge.

I've had trouble connecting my Trezor to Electrum in the past, and was able to solve the issue by installing the Trezor Bridge.  To download the Trezor Bridge you'll need to access the page by using Chrome, Chromium, or the FireFox browser.  If you try to access the page with IE or Edge it'll tell you your browser is not compatible.

Here's the link to download the Trezor Bridge: https://suite.trezor.io/web/bridge/
