Enable WebUSB or Use Bridge

Permissions & Browser Settings
- Allow the browser to access USB devices when prompted.
- Disable conflicting browser extensions (some wallet extensions may conflict).
- Restart browser after installing Bridge.
Recommended Checklist
- Install latest Trezor Bridge from official site.
- Use updated browser (Chrome, Brave recommended).
- Reconnect device and verify on-device prompts for authenticity.
