SDCARD nao reconhecido XUbuntu

Não estou conseguindo acessar um cartão de memória q comprei. Insiro o cartão, e ele sequer da sinal de vida. Troquei por outro e a mesma coisa.
Quando coloco o cartão em um pc que usa Windows ele abre normalmente.
Meu cartão de memória é um Sandisk ultra 16 e 32GB(testando os dois). Como resolver este problema.
1) No fdisk ele nao aparece
2) Ja tentei a solucao exfat-fuse e nada.
3) Ja tentei ntfs-3g e nada.
4) Ja tentei a solucao de adicionar tifm_sd no arquivo sudo gedit /etc/modules e nada.
5) Atualizado Ubuntu e nada: sudo apt-get update && sudo apt-get -u dist-upgrade
6) E nada...ja desistindo

Se ele não aparece nem no fdisk então pulemos pro dmesg e lsusb

lsusb 

dmesg

 

Poste uma print do dmesg, o cartão SD deve aparecer nos últimos logs, veja meu exemplo:

Also, esse SD tá sendo lido por um adaptador ou alguma porta específica pra ele?

Ele eh espetado direto em uma entrada no notebook(sem adaptador). A sainda do meu comando dmesg eh diferente da sua. As ultimas linhas sao essas(troquei alguns numeros por questoes de seguranca):
Aparentemente, nao ha nenhuma referencia ao hw do sdcard.

Ja o lsusb retorna isso:

olha, nos meus micros, cartão de memória só lê se for espetado num leitor de cartão, este por sua vez, espetado numa porta USB. meu adaptador é um Aero Sim Multislot Card Reader.

Mas nos seus comandos, vê-se que seu linux não enxerga o cartão de memória.

pelo jeito, seu notebook tem uma "porta" para cartão, direto no gabinete.

qual a marca e modelo do notebook? Já procurou na rede se ele precisa de um driver linux, para enxergar o cartão?
