An meinem Netbook Asus F200MA funktioniert nach Installation von Ubuntu 14.04 der interne Card-Reader nicht (Karten werden nicht erkannt). Eingebaut ist offenbar ein Realtek 5286 Card-Reader:

Der Fehler und eine Lösung sind bekannt: https://bugzilla.kernel.org/show_bug.cgi?id=67491
Da die dort beschriebene Lösung etwas zeitraubend nachzuvollziehen ist, hier ein Schnelldurchgang, der in der beschriebenen Installation funktioniert:
wget https://bugs.launchpad.net/ubuntu/+source/udisks/+bug/971876/+attachment/2991730/+files/rts_bpp.tar.bz2 tar xvjf rts_bpp.tar.bz2
in ~/Downloads/rts_bpp die Datei rtsx.c mit einem Editor öffnen, den Inhalt mit folgendem Code ersetzen und speichern:

Der von Ubuntu verwendete Treiber wird deaktiviert, indem in /etc/modprobe.d die Datei rtsx_blacklist.conf mit dem Inhalt "blacklist rtsx_pci" erzeugt wird.
Die Installation des neuen Treibers erfolgt mit:
cd /home/Downloads/rts_bpp make sudo make install sudo depmod -a
Jetzt sollten Speicherkarten erkannt werden.
