Mageia 2 no me detecta el escáner de mi HP-PSC-1315

Hoy necesitaba escanear unos documentos y me he encontrado que Mageia 2, 32bits, no me detecta / no me enciende el escáner de mi impresora HP-PSC-1315. El caso es que el sistema detecta la impresora:

Y le he instalado xsane y varios más:

[root@localhost ~]# rpm -qa | grep sane
sane-backends-iscan-1.0.22-7.mga2
libksane-4.8.2-1.mga2
libsane1-1.0.22-7.mga2

sane-frontends-1.0.14-12.mga2
sane-backends-1.0.22-7.mga2
xsane-0.998-2.mga2

He reiniciado la sesión de KDE4 y sigue sin funcionar.

¿Alguna idea? Gracias...
