Electrum+Ledger NANO. How?

[onealfa]

Hi.
Anyone has some reference where to find info, how to use Electrum with LEDGER WALLET NANO ?
What ever i try - all fails
There is some topic on reddit, abt HW.1 use, but all links there are dead. Not much use of it.

What operation system do you use?
At what step exactly do you fail?
Did you already initialize the ledger with a seed?

I use WIN-10 64 bit. ASUS K56C
This is with NANO connected, and loged in:

 Similar while NANO unplugged from USB
Pretty much the same, while trying to create new wallet, not only restoring.
Same on USB2 and USB3 ports
NANO  has been already initialized with seed

I had the same problem on Windows. :-(
Went to Ubuntu and had it running in no time.

Sorry I can't help you with Windows but if you would like to use Ubuntu I can point you to the ppa you need to install to get the btchip and python binaries.

Seems i got no option...even with my tiny Linux experience...i would like to try that.
Since I got a dedicated UBUNTU notebook already.... yet not very familiar with it.

The quick way is to use Richard Ulrichs ppa
https://launchpad.net/~richi-paraeasy/+archive/ubuntu/bitcoin

1. open the terminal
2. add the ppa

Code:

sudo add-apt-repository ppa:richi-paraeasy/bitcoin

3. update to the latest list

Code:

sudo apt-get update

4. install the necessary packages

Code:

sudo apt-get install pyusb btchip-python python-hidapi

5. open electrum and create a wallet from an existing Ledger Wallet

After step 4 i got this:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package pyusb
E: Unable to locate package btchip-python

I'm new to Linux, and all my attempts to solve this (install these 2 packages) = were totally unsuccessful

What computer are you using?
What is the CPU architecture?
i386, x68_64, arm,...

I tried so many variations before - all no luck (win7 win 10 x64, TAILS, UBUNTU 32 bit)
The last attempt was on
ASUS K56CB
Intel® Core™ i7-3537U CPU  RAM= 6GB
OS : 64 bit  UBUNTU 15.10
I even purchased a new SSD 180GB for this, and made a clean fresh install  of UBUNTU on it
Nothing works....

When you tried under Windows 7 did you use the most current pre-built binary (2.5.4) or did you compile from the source? I'm running the pre-built binary under Windows 7 with a Ledger HW.1 and it works perfectly.

Have you tried the Ledger Nano with any other wallets (I.E. the Ledgerwallet plugin for Chrome) that is the default native wallet? The Copay plugin also works if you use it to build a multi-sig wallet.

If it doesn't work with either of those then it may be possible you have a bad USB port of a defective Nano.

Another user, similar problem ... at least partially.

First I've got the same problems as described before.
(Windows 7, Electrum 2.5.4 (pre-build), Ledger Nano, works fine in the chrome app)

After a reboot - windows told me so after installing the ledger driver, even the chrome ledger app worked fine withour a reboot - the error situation is slightly different.

New Wallet
  -> Restore ... & Hardware Wallet
  -> Ledger Wallet
  -> failed (No device ...)

New Wallet
  -> Create new Wallet & Hardware Wallet
  -> Ledger Wallet
  -> Request to enter PIN (Number of tries)
  (Wallet created, public keys seem to be imported)
  -> Device not found (Watch-only mode)
  (existing Transaction was shown)

Any ideas? Hints? Something to try out?

Win 7, Electrum 2.5.2 (pre-build)
now Win 10, Electrum 2.5.4 (pre-build)
Ledger Nano is fine, works good with Chrome app,  and good with clean boot starter
In fact - i've got two NANO's, both behave the same
USB ports are OK too, tried USB2.0 and USB3.0

After a few more tries - some removings of the token and restarts of Electrum (which hung up two times and could only be abborded via Taskmanager) - it works now. I have no idea, what is different now, but well, as long as it remains working, that's fine for me.

After using the token with the chrome app, I have to close the app and to remove the token from USB. Then I have to insert the token and afterwards to start Electrum. Then the PIN request comes and afterwards it works. (I'm sure, I've also tried it like this before (without success), but now it works as expected.

It reminds at the work-around strategy for Windows to shutdown and restart to solve certain problems. That's not a satisfiable strategy for computer specialists, but it seems that it solves this problem too (hopefully permanently).

It appears that the Ledger has to be removed and re-inserted between invocations of Electrum (and the Chrome app as well). I just tried the scenario you just described and was able to re-produce the results. If I leave the Ledger installed, stop and re-start Electrum, I also get "device not found". If I stop Electrum, remove and re-insert the Ledger, and then restart Electrum it works.
