Udev rules don't work on Ubuntu 21.10

[billytetrud]

My user is also apart of the plugdev group, but no love. Eg attempting to connect my trezor at https://adalite.io/ does not recognize the device after I put my pin in.

FYI, I have not gotten this fixed. A colleague on Ubuntu 20.04.3 LTS had a working ledger until upgrading the firmware. It seems likely this is a firmware bug and unlikely a udev rules change would help. FWIW I tried adding this kind of stuff to the udev rules: https://forum.electro-smith.com/t/web-programmer-securityerror-access-denied-on-linux-solved/192 which I noticed Trezor's rules have, but didn't help (also didn't hurt - ledger live could still connect fine).

i ve used ledger-live for two years on Win7 no problem, though since the latest upgrade to both version 2.49.2 & 2.50 i ve had no luck reaching nano - I've removed all previousley installed drivers and reinstalled both apps on Win and Linux hosts, both have failed to detect nano - luckily though the mobile version still works .. for how long though im not sure .

• imho Ledger-Live has bloated more features more bugs & vulnerablities -
  you can't use Trezor's rules the vendor codes won't match -

https://wiki.archlinux.org/title/udev :

"udev's main purpose is to act upon peripheral detection and hot-plugging, including actions that return control to the kernel, e.g., loading kernel modules or device firmware. Another component of this detection is adjusting the permissions of the device to be accessible to non-root users and groups.

As the successor of devfsd and hotplug, udev also manages device nodes in the /dev directory by adding, symlinking and renaming them. udev replaces the functionality of both hotplug and hwdetect. "

I found something Ubuntu has Ledger's udev rules in its repo

• i'm on Ubuntu 22.04 and on the app Discover they're listed as;
• ledger-wallets-udev
  ; )

have yet to install em & run the app.... but in tthe meantime you could do the same
