Recentemente eu comprei um Lenovo Z400 com tela sensível ao toque e trabalhei perfeitamente no Windows 8 que veio com ele. O problema é que não consigo usá-lo no Linux (estou usando o Fedora 20).
No meu dmesg eu tenho uma menção sobre isso, mas no meu lsusb eu não consigo nada. Não tenho certeza de qual versão ou modelo é.
Bem, abaixo está a saída do lsusb:

... mas eu encontrei uma menção na saída do dmesg:

Eu também tentei um live-dd do Ubuntu 14.04, mas não funcionou nem apareceu na saída do lsusb.
