Has anyone used their HW.1 with Electrum 2.4 on Ubuntu? Is there a guide available anywhere?
there is a (slightly outdated) guide here : https://www.reddit.com/r/coincode/comments/336f08/ledger_hw1_review_and_guide_for_use_welectrum/i have a duo hw1 and have set both up to use the same seed and can pair multiple devices to the wallet. however, it appears transaction authorisations are only push out successfully to the last paired device. is there a way to get this to work for more than one paired device?
checking that with the right team and I'll let you know |

checking that with the right team and I'll let you know thanks. also, I came across this article today http://www.wired.com/2015/07/brainflayer-password-cracker-steals-bitcoins-brain/. would our hd wallets and the 24 word secret phrase we use to generate the private key for ledger and hw.1 be affected by this? |

that's not a risk, brainwallets are easy to crack because the passphrase is the entropy of the seed, and we are not a very good source of entropy. The mnemonic phrase works the other way round : the words encode the entropy of the seed, which is chosen by a proper random generator. |

I joined the mycelium beta program and just downloaded the latest release from the play store. This update is new since 12 hours ago, and lists Ledger Nana, HW1 and unplugged support, and coinapult support. I can confirm the coinapult support is there when I add an account, but I can't see Ledger support anywhere. The Cold storage option only has Sign with Trezor. With HW1 + OTG I get to Trezor okay - scanning accounts, and nothing happens from there ..... |

Make sure you visited the other link after joining the group. It should be in Advanced / Ledger when you scan - also recheck the version number at the bottom of Mycelium app - Android betas are quite horrible to install if you have multiple accounts on your phone as the Play Store will point you to random versions depending which account you're signed on with (which you can't really control)

Running version 2.5.0 Under :. Settings At the very bottom is "Ledger Hardware Wallet", the only tick box there is "Disable TEE support" Settings > Advanced Settings only has "Use tor-Network" No Ledger option in :. Cold Storage Edit : helps if you read the manual ! Just uploaded a new version of the current 2.5.0 Beta, which now includes Ledger support - you can import accounts from Ledger Nano, HW.1 and (the not yet release) Ledger Unplugged (NFC card).
To test the new option, go to the Account-Tab, click the [add] Button and go to the [Advanced] section. Here youll find a new [Ledger] Button. Plug in your Ledger via an OTG-Cable and import an account. Works ! Is the Mycelium/Ledger GUI limited to 4 digit PINs, or if I have setup a longer one will it allow me to enter >4 digits ? |

I'd say it's limited to 4 digits since the Chrome app works with 4 digits, but I can't really remember.

If you get the latest Greenbits or Mycelium beta and a Galaxy S6, S6 Edge, S6 Edge Plus, Note 5, or an Exynos CPU Note 4 (SM-N910C and SM-N910H), you can also test Ledger Trustlet, a virtual hardware wallet you can download for the Trusted Execution Environment of your smartphone - more details on https://www.ledgerwallet.com/beta/trustlet |

Ahh!!! That's why it's not working with my tablet! It was working until I paired my new phone and now it only works with the phone. |

Still hasn't received my BTCChip.  Any idea WHY? Was there any technical issues on the service you used to ship? OR will it receive soon? I had hope that it will but now it is approximately 1 month, my hope has gone. I have no complains on this company. Take that 0.05 BTC as my donation.   Best Of Luck! ~~MZ~~ yeah, I'm afraid it looks like I'm beta testing the post office delivery to non European / US countries. I'll resend it tomorrow using a different service, sorry for the delay. Remember the one you send for first time? It reached its destination 2-3 months ago but the receiver informed me very recently. What should I do? Sending back is certainly not a good idea. Should I pay you or sell it to someone else and send you the money? * Edited. |

I thought that had been solved, will talk about it with the team Remember the one you send for first time? It reached its destination 2-3 months ago but the receiver informed me very recently.
it's ok, you can give it to someone needing it |

looks like i'm a victim of this malleability i read about here: http://cointelegraph.com/news/115374/the-ongoing-bitcoin-malleability-attackis there anything i can do to sync my hw1 ledgerwallet to show the correct amount? at the moment I have a transaction that has been duplicated. it was a simple funds movement between accounts on my hw1. one transaction has cleared and the other is unconfirmed. the consequence is one of my wallets reads as balance of 0.5 btc but has a usd balance of -118.38 (because of the duplicate spend) and the other obviously has too much funds in it. but i believe the total funds across all wallets are correct. |

Is there a way to create more than 1 new address (within the same account)?
For example if I want to ask multiple people to pay later with each having his individual address so that I can track who actually paid.
I have tried with the Ledger Wallet Chrome app and Mycelium but they only give me the next address and as long as no transaction is registered on it I can't get a new one.

You have a BIP32 xpub, so just use a tool like this: https://bitcore.io/playground/#/hdkeys |

you do it on Ledger Wallet Chrome app through the API - https://www.ledgerwallet.com/api/demo.html use "Get Xpub" with the BIP 44 path (44'/0'/0'/0/x with x being the index, for the first account) |

Thanks for your replies. This way I can create new pulic keys even without having the ledger wallet with me. On the other hand if my xpubkey is leaked then all the future public keys for all my accounts could be generated by a third party, right? This looks to me as the easiest and safest way to do it for now. |

No, only one account privacy will be compromised as you have to get an xpub per account (the account index being an hardened BIP32 derivation) |
