usbguard-alert

Actionable desktop notifications for USBGuard. When USBGuard blocks a USB device, a notification appears with three buttons: Always Allow, Allow Once, and Ignore (reject for this connection). Prompts show the device ID, serial (if reported), port, and USB interface classes (HID, mass storage, ...) and remain until acted on or dismissed.

Install

On Arch Linux:

makepkg -si                                           # or: make && sudo make install
sudo usbguard add-user "$USER"                        # allow IPC access
systemctl --user enable --now usbguard-alert.service
journalctl --user -u usbguard-alert.service           # logs

Build and test

Building requires base-devel, glib2, libnotify, and systemd; hwdata and usbguard are needed at runtime.
