The package has been added to the repo as of 2025-03-27T23:00:00Z
It can be synced using
sudo pacman -Syu udev-usb-sync
To avoid confusion with our repo - the package on AUR has been renamed to arch-udev-usb-sync - so anyone having the old AUR build should be automagically synced to the repo version.
//EDIT
2025-04-02T05:45:00Z:
On March 30. 2025 the package was added to the Packages-Root and thus Manjaro 25 release review after that date will default to use the helper.
