Ledger Not Recognised by Computer: Complete Fix Guide (2026)
Quick Checklist First
Before going through full solutions, check these basics:
- ✅ Is the Ledger powered on? (It should show a screen when connected)
- ✅ Is the correct app open on the Ledger? (For Ethereum, the Ethereum app must be open)
- ✅ Is Ledger Live up to date? (Check for updates in the app)
- ✅ Are you connecting via USB, not just charging?
Fix 1: Try a Different USB Cable
This is the most common cause. Many USB-C cables are charge-only — they carry power but not data. Ledger devices require a data cable.
- Use the cable included in the Ledger box
- If you’ve lost it, any USB-C cable labelled “USB 3.0” or “data + charge” will work
- Avoid cheap phone charger cables
Fix 2: Try a Different USB Port
USB hubs, USB extenders, and some front-panel ports on PCs don’t reliably pass data. Try:
- A different port on the same computer
- A rear USB port on a desktop (these are directly on the motherboard)
- A different computer entirely, to rule out computer-specific issues
Fix 3: Windows — Install the Device Driver
Windows sometimes fails to recognise Ledger without the correct driver.
- Connect your Ledger
- Open Device Manager (search for it in the Start menu)
- Look for an Unknown Device or a device with a warning icon
- Right-click → Update driver → Search automatically
Alternatively, uninstall and reinstall Ledger Live — the installer includes the necessary drivers.
Fix 4: macOS — Allow the Connection
macOS Ventura and later may prompt you to approve a new USB device.
- Go to System Settings → Privacy & Security
- Look for a message about a blocked device
- Click Allow
Also check: System Settings → Privacy & Security → Full Disk Access — Ledger Live may need permission on some macOS versions.
Fix 5: Reinstall Ledger Live
A corrupted Ledger Live installation can cause detection failures.
- Uninstall Ledger Live completely (including app data if prompted)
- Download the latest version from ledger.com/ledger-live
- Install fresh
- Connect your Ledger and try again
Fix 6: Update Ledger Firmware
If your device is running old firmware, it may not be fully compatible with the current Ledger Live version.
- Open Ledger Live
- Go to My Ledger tab
- If a firmware update is available, install it
- If the device isn’t detected in Ledger Live, try the Ledger Recovery Check mode (hold the button while connecting for Nano S Plus; instructions in the Ledger Live onboarding)
Fix 7: Check Security Software
Antivirus or firewall software occasionally blocks Ledger Live from communicating with the device.
- Temporarily disable your antivirus and try again
- If it works with antivirus disabled, add Ledger Live as an exception
- Common culprits: Avast, McAfee, Kaspersky
Fix 8: Use a Different Browser (for MetaMask/Web3)
If you’re trying to connect Ledger to MetaMask or a web3 site (not Ledger Live):
- Use Chrome or Brave — these have the best WebHID/WebUSB support
- Firefox has limited hardware wallet support
- Make sure the Ethereum app is open on the Ledger device
- Check that MetaMask has the Ledger extension installed if using WebHID
Fix 9: Ledger in Bootloader Mode
If Ledger Live shows the device but can’t communicate properly, try bootloader mode:
Nano X / Nano S Plus:
- Unplug the device
- Hold the left button while plugging back in
- The device enters bootloader mode (shows a boot screen)
- Open Ledger Live — it should detect it in repair mode
This allows firmware reinstallation even if the device seems stuck.
Still Not Working? Contact Ledger Support
If none of the above resolves the issue:
- Go to support.ledger.com
- Chat support is available and generally responsive
- If the device is defective and under warranty (2 years), Ledger will replace it
Frequently Asked Questions
My Ledger shows on screen but Ledger Live says “No device detected” — why?
The most common causes: wrong USB cable, correct app not open on the device, or a Ledger Live update needed. Check all three.
My Ledger worked yesterday but not today — what changed?
Possible causes: a Windows/macOS update that affected USB drivers, a Ledger Live update that needs a firmware update to match, or a cable going bad. Start with a different cable and different port.
Can I use Ledger without Ledger Live?
For MetaMask and web3 use, yes — you connect directly through the browser. But for firmware updates and initial setup, Ledger Live is required.
My Ledger screen is blank when connected — is it broken?
If the screen is completely blank (no logo, no PIN prompt), the device may not be receiving power — check the cable and port. If it powers on but shows only a lock/PIN screen, that’s normal — enter your PIN.
