Eu instalei o Ubuntu 14.04LTS e foi impossível usar o buit no leitor de cartão SD. Eu encontrei algumas soluções relacionadas aqui, mas nenhuma funcionou. Alguns poucos resolveram esse problema baixando o driver realtek. Mas, eu não sou certo que o leitor de cartão SD é um realtek.
também instalou o pacote libccid mas não usa ..

¿é o PCI bridge: Intel Corporation ValleyView PCI Express Root Port do leitor de cartão SD? parece que está usando um driver, mas não está funcionando ...
coult porque eu mudei isso no grub ?: link
Parece que há um sofrimento comum com os cartões SD, por isso espero que a solução do meu caso possa ser útil para a comunidade.
Felicidades!
