Who this guide is for

This page is for people using a hardware wallet with MyEtherWallet (MEW) or MyCrypto who see connection failures such as myetherwallet ledger error, myetherwallet ledger not working, or the specific myetherwallet ledger error code 5 message. I write from hands-on testing across browsers and platforms, and from helping others untangle the same problems. Expect quick fixes first, then deeper diagnostics and worked examples.

Common symptoms and quick checklist

Symptoms you might see:

Quick checklist (try these before anything complex):

  1. Unlock the hardware wallet and open the Ethereum app on the device.
  2. Use a known-good USB cable and switch USB ports.
  3. Close other wallet apps and browser extensions (MetaMask often conflicts).
  4. Try an incognito/private window with extensions disabled.
  5. Test another browser or another computer to isolate the issue.

If you search for "my ether wallet ledger" errors online you'll find the same checklist repeated — because many issues have simple causes. And yes, a cable swap often fixes it.

Step-by-step troubleshooting (quick fixes first)

Follow this ordered flow. Work from top to bottom.

  1. Disconnect the device. Wait five seconds. Unlock the device and open the Ethereum app, then reconnect.
  2. Close desktop companion apps and all browser tabs that might access the device.
  3. In MEW/MyCrypto select the hardware wallet option and follow the Ledger connection flow (pick the WebUSB or U2F option if shown).
  4. If you still see nothing, open a browser private window and try again (extensions won’t run there).
  5. If it still fails, reboot the computer and retry on a different USB port.

Worked example: On a Windows laptop I saw MEW time out. I closed the companion app, unplugged the cable, unlocked the device, opened the Ethereum app, then reconnected. MEW detected the device immediately.

Specific: myetherwallet ledger error code 5 — what to try (and a fix list)

If you're specifically looking for a myetherwallet ledger error code 5 fix, try these targeted steps. Error code 5 commonly appears when the browser can’t open a proper USB session or when another application is holding the device.

Try this ordered list:

If error code 5 persists, collect exact steps (OS, browser version, cable type, whether device shows on the OS) and consult the error-codes-index or transaction-failures-stuck pages for deeper diagnostics. But don’t rush updates — confirm your device shows expected prompts before approving anything.

Root causes mapped to fixes (table)

Symptom / Error Likely cause Action to fix
No device found Device locked or wrong app active Unlock device and open Ethereum app
Timeout / code 5 Browser USB permission or another app has device open Close apps, switch WebUSB/U2F, try incognito
Empty account list Wrong derivation path or active passphrase Try alternate derivation paths; check passphrase (25th word)
ERC-20 signing fail Smart-contract data not allowed on device Approve contract data / smart contract interactions on the device app (follow prompts)
Intermittent connect Faulty cable/port or power-savings issue Replace cable, use direct port, disable USB power saving

Firmware, apps, and safety when updating

Firmware and app version mismatches produce connection and signing errors. In my testing, older device apps often behaved poorly with updated web wallet libraries.

Safe update rules:

If you run into update-related problems, check the companion-app troubleshooting page (ledger-live-issues or similar) before attempting recovery.

USB vs Bluetooth vs Mobile — connection notes

USB is the most reliable path when using MEW/MyCrypto on desktop. Mobile flows and Bluetooth introduce different failure modes.

But remember: convenience comes with trade-offs. For high-value transactions I prefer to sign over a direct USB connection or an air-gapped workflow.

Advanced: derivation paths, passphrase, and account visibility

Address visibility issues often come from derivation path or passphrase mismatches.

For multisig or custom setups, consult multisig-setup and wallet-integration-hub to confirm compatibility.

FAQ — real user questions

Q: Can I recover my crypto if the device breaks? A: Yes. Your crypto is controlled by your private keys, recoverable from your seed phrase using compatible wallets. See recover-from-seed for step-by-step guidance.

Q: What happens if the wallet company goes bankrupt? A: If you hold your seed phrase (and any passphrase), you retain access to funds. Read lost-device-company-bankrupt for legal and inheritance planning.

Q: Is Bluetooth safe for a hardware wallet? A: Bluetooth increases attack surface. For convenience it's fine for small transactions, but for long-term cold storage or large transfers stick to USB or air-gapped signing. See connectivity-security.

Wrap-up and next steps

When MEW/MyCrypto reports a connection error with your hardware wallet, start simple: unlock the device, open the Ethereum app, swap cables, and try an incognito browser session. Escalate to firmware and derivation-path checks only after the basics are exhausted. I believe a calm, methodical checklist saves time and reduces risk. What I’ve found: gather reproducible steps before contacting support — it speeds up resolution.
