Use Arch’s Current Device-Access Model
Ledger Live Arch Linux udev rules should be assessed against the actual Arch system and current publisher rules. Ledger Wallet is the current application name. Copying an old Ubuntu group instruction does not establish that Arch will grant access to your active desktop user.
Start by recording the exact error and connected hardware information. A device absent from USB enumeration cannot be repaired by a matching rule that never receives its event. A busy device and a denied device file also require different follow-up.
Compare Rule Contents With the Publisher Reference
The LedgerHQ rules repository identifies the current upstream entries. Review the file and method before authorizing installation. Check for older local copies, conflicting rules and an incorrect filename extension.
Use hardware attributes to establish which entry applies. Do not permanently match an accidental hidraw node number, because that assignment can change after reconnection. Avoid creating a permissive rule for all input devices just because the Ledger’s error mentions HID.
Check Rule Order and the Active Session
The ArchWiki udev reference explains current session-based access and rule ordering. Rules using uaccess need the appropriate order relative to the system’s later access processing. Have an administrator compare the installed filenames and policy instead of assuming file presence proves the desired result.
Also identify the session running the wallet. A remote shell, an inactive user and the local active desktop can have different access conditions. A test performed as root is not equivalent to normal-user access and should not become the daily launch method.
Apply and Retest One Relevant Event
Rule configuration, loading and device-event processing are distinct stages. The upstream udevadm manual documents the relevant inspection tools. Use targeted administrative actions for the actual device rather than triggering broad unexplained changes across the system.
For an idle ordinary session, reconnection can provide a fresh event after a relevant correction. Keep an actively progressing Ledger OS installation connected and uninterrupted. Note the resulting device attributes and whether the original access failure still occurs.
Do Not Confuse udev With AppImage Startup
If the wallet never opens, capture the earlier runtime error first. Arch’s fuse2 package reference addresses a separate dependency question for compatible AppImages. A successful package installation does not prove that USB rules match or that Ledger officially supports every Arch configuration.
Once the normal interface launches, request one nonfinancial hardware action. If permissions work but another client has the device open, isolate that session. If hardware access succeeds but public account history fails, investigate the network or asset service independently.
After an Arch system update, retain the installed systemd version alongside the rule filename and its contents. That does not prove a regression, but it makes an access-model change assessable. Compare current distribution instructions before recreating a group or copying rules from an old machine. A rule that once worked elsewhere is evidence to review, not a permanent compatibility guarantee.
Arch Device-Access Questions
Should I add a plugdev group because a tutorial says so?
Do not assume that group is the current Arch solution. Check the distribution’s documented access mechanism and the installed rules. Historical group recipes can target a different policy model.
Can I change permissions on every hidraw node?
That affects unrelated peripherals and may disappear when nodes are recreated. Resolve the matched hardware access through the appropriate targeted rules rather than using broad permissions.
Does account discovery need my recovery words?
The configured Ledger can provide supported account information through its normal connection. Recovery words do not belong in Arch commands, downloaded rule installers or support forms, and hardware initialization is not a udev repair.
