ELAN Touchscreen no Ubuntu 14.04 e Debian 7.6

Question

Eu comprei recentemente um laptop ASUS Q550LF com o Windows 8.1 pré-instalado e, posteriormente, instalei o Ubuntu 14.04 e o Debian 7.6. Eu uso o Ubuntu para a maioria das tarefas, mas ocasionalmente tenho razão para iniciar o Debian. O problema é que o Debian não inicializa. Em algum momento durante o processo de inicialização, recebo variações nas seguintes mensagens de erro:

[time] usb 1-7: unable to read config index 0 descriptor/start: -71
[time] usb 1-7: can't read configurations, error -71

[time] usb 1-7: unable to read config index 0 descriptor/start: -110
[time] usb 1-7: can't read configurations, error -110

Repetem indefinidamente e o processo de inicialização é interrompido. Eu não tenho problema com a tela sensível ao toque no Windows ou no Ubuntu, então suspeito de algum problema com o Debian. Ao inicializar o Ubuntu, a mesma mensagem de erro ocorre, mas eventualmente a tela sensível ao toque é reconhecida:

Não consigo desativar a tela sensível ao toque no BIOS, e a maioria das soluções que encontrei ao pesquisar o problema não funciona. Eu nem tenho certeza de como eu resolveria o problema. Se alguém pudesse me apontar na direção certa, eu agradeceria. Obrigado antecipadamente!

Todos os dispositivos USB têm energia suficiente para fazer o que quiserem quando tudo está conectado? Funciona se você desconectar todos os outros dispositivos USB?
