If you connect a Trezor and the computer cannot find it, follow these steps.

  • Download the Zadig USB drivers.
  • Install them on your machine.
  • Connect the Trezor to the computer while holding both buttons down, then release the two buttons afterwards.
  • Open Zadig, choose "Option" from the top menu, and select "List all devices".
  • For the device listed, choose "Unknown Device #1" or something close to it.
  • To the right of the green arrow, choose "libusb0 (v1.2.6.0)" from the options.
  • Click the option that says "Install Driver" or "Replace Driver".
  • Wait until it finishes, then close Zadig.
  • Unplug the Trezor and go to the wallet on the Trezor website.

That is all it takes for the computer to find the Trezor.

If you have further questions you can contact SIAMBC at order@siambc.com.
