Ledger Live Version and Operating System

  • Tested on Ledger Live 2.2.4

Device detected but connection failed. Please try again or contact us if the problem persists.

==> I think it's a bug because I can synchronize my Ledger with Windows 10 without any problem <==

Steps to reproduce the behavior


I launch Ledger live (the .appImage), I connect my ledger nano s, I enter the pin, then I have the error
"Device detected but connection failed. Please try again or contact us if the problem persists."

I tried to clic "Repair" and I tried to remove my personnal config in ~/.config/Ledger\ Live but I'm still unable to synchronize..

I will let the full log below, there is a message : "cannot open device with path /dev/hidraw4" (sometime it's on /dev/hidraw6) so I assume this is a usb problem with Ubuntu, If you guys got an Idea about my problem ?


Here is the complete log I got :

I've managed to solve my problem. There was a problem with permissions :

Before

$ ll /dev/hidraw4
crw------- 1 root root 242, 4 avril 22 14:53 /dev/hidraw4

So, when I launched my Ledger app as a simple user I didn't have enought rights to open and manage this device.

I tried to launch Ledger Live app with sudo/root but there is a security protection :

$ sudo ./ledger-live-desktop-2.2.4-linux-x86_64.AppImage
[29334:0422/144804.342370:FATAL:electron_main_delegate.cc(211)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

The solution

$ sudo chmod 666 /dev/hidraw4

And this "workaround" solves my problem. I don't know where this problem come from Ubuntu, Hidraw, or Ledger Live App...?

Solution above didn't work for me. But this support site from Ledger offers a fix: https://support.ledger.com/hc/en-us/articles/115005165269-Fix-connection-issues

$ wget -q -O - https://raw.githubusercontent.com/LedgerHQ/udev-rules/master/add_udev_rules.sh | sudo bash

Keep in mind if you fix the ledger issue by changing the permissions on /dev/hidraw* and you try to update the firmware, the update will not work until you give permissions to the new hidraw* device, otherwise the update will be stuck on the "updating" screen.
