Document Scanner) does not detect it. ## Steps to reproduce 1. guix install simple-scan 2. Connect the scanner. 3. Launch Simple Scan. 4. Click the Scan button in Simple Scan. ## Unexpected behavior In step 3, Simple scan displays the following warning: ``` No scanners detected Please check your scanner is connected and powered on ``` In step 4, you see the following message: ``` Failed to scan No scanners available. Please connect a scanner. ``` ## Expected behavior * The scanner is detected in step 3 (no warning message is shown). * Performing step 4 makes the scanner scan. ## System information I'm using the Guix System and simple-scan 3.34.1: ``` $ LANG=C guix describe Generation 5 Nov 04 2019 14:24:15 (current) guix bf7b08c repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: bf7b08c4fe7d14c25a83bde99f19eca1119d88ff ``` ## Additional information The scanner works. I can use it from a Trisquel 8 Live USB stick, which comes with Simple Scan. Running simple-scan from a terminal displays the following warnings: ``` $ LANG=C simple-scan (simple-scan:3953): Gtk-WARNING **: 18:42:44.193: Failed to register client: GDBus.Error:org.gnome.SessionManager.AlreadyRegistered: Unable to register client ``` --- https://sirgazil.bitbucket.io/
