If your BitBox is not connecting to your computer or is not detected by the BitBoxApp, the issue is usually related to the USB cable, USB port, operating system, security software, or BitBoxApp setup.

This guide helps you complete the most important general checks first. If the issue is specific to your operating system, you can then continue with the dedicated macOS, Windows, or Linux guide.

This article applies to BitBox hardware wallets connected via USB, including BitBox02 and BitBox02 Nova.

Before you start

Before troubleshooting your USB connection, make sure that:

you are using the latest version of the BitBoxApp, and

the firmware on your BitBox is up to date.

Outdated BitBoxApp or firmware versions can prevent your BitBox from being detected correctly, even if the USB connection itself works.

Quick checks

Start with these basic checks. They resolve many USB connection issues.

1. Try a different USB cable.

2. Connect your BitBox directly to your computer.

3. Avoid USB hubs, docking stations, adapters, or extension cables during troubleshooting.

4. Try a different USB port.

5. Connect your BitBox so that the screen is facing up.

6. Restart your computer.

7. Test your BitBox on another computer or Android smartphone, if possible.

If your BitBox works on another device, the BitBox itself is most likely working correctly. The issue is probably related to your original computer, USB port, adapter, operating system, or software setup.

Check the most common software causes

If the quick checks did not help, continue with these general software checks.

1. Close the BitBoxApp.

2. Disconnect your BitBox.

3. Restart your computer.

4. Open the BitBoxApp again.

5. Reconnect your BitBox.

6. Temporarily disable antivirus software, firewall tools, VPN tools, or endpoint security software for testing.

7. Re-enable your security software immediately after testing.

8. If disabling security software helps, add the BitBoxApp to the allowed list.

9. Download and reinstall the latest version of the BitBoxApp.

Only disable security software temporarily for testing. Re-enable it immediately afterward. If it blocks the BitBoxApp, add the BitBoxApp to the allowed list instead of keeping protection disabled.

Check whether your operating system detects your BitBox

Even if the BitBoxApp does not show your BitBox, your operating system may already recognize it as a connected USB device.

This distinction is important:

If your operating system does not detect your BitBox, the issue is likely related to the USB cable, USB port, adapter, or physical connection.

If your operating system does detect your BitBox, but the BitBoxApp does not, the issue is more likely related to permissions, drivers, the BitBoxApp installation, or blocking software.

Choose your operating system below and continue with the dedicated guide.

macOS

If you use macOS, check whether your Mac detects your BitBox in System Information or through the Terminal app.

Windows

If you use Windows, check whether your BitBox appears in Device Manager and whether the hardware IDs match the BitBox USB device.

Linux

If you use Linux, check whether your BitBox appears with lsusb. If Linux detects your BitBox but the BitBoxApp does not, the issue is usually related to missing udev rules or USB permissions.

Why does my computer detect my BitBox, but the BitBoxApp does not?

If your operating system detects your BitBox but the BitBoxApp does not, the issue is usually related to the BitBoxApp installation, missing permissions, drivers, or software that blocks USB communication.
