Issue description

Steps to reproduce

• set hardware.ledger.enable = true;
• and install ledger-live-desktop
• try using connecting a Ledger hardware wallet to Ledger Live.

Info

There have been some changes to Ledger's udev rules and the most recent ones can be found here:
https://github.com/LedgerHQ/udev-rules/blob/master/20-hw1.rules
More information about the change can be found via the commit history.

I've actually added those rules to services.udev.extraRules and it's working.
