My Trezor won’t connect — what should I do?

Why this happens

Hoseki uses the official Trezor Connect libraries. If your device firmware or Trezor Suite is out of date — or another app already has the device in use — the browser may not be able to connect to your Trezor.

Step-by-step

  1. Make sure nothing else is using your Trezor
    • Quit Trezor Suite (don’t just minimize it).
    • Close other wallet/exchange apps or browser tabs that might access hardware wallets.
    • Unplug and re-plug your Trezor directly into your computer (avoid USB hubs if possible).
    • Try a different USB port or cable if available.
  2. Update Trezor Suite
    • Open Trezor Suite and check for updates.
    • Install the latest version, then fully quit and relaunch Suite once.
  3. Update your device firmware
    • With Suite open, connect your Trezor and follow the prompts to update firmware.
    • After the update finishes, quit Trezor Suite so the browser can access the device.
  4. Retry in your browser
    • Reopen Hoseki and connect your Trezor when prompted.
    • If you have multiple browsers, try Chrome first (WebUSB support is most reliable there).
    • Approve USB permissions when the browser asks.
