O meu scanner funcionava normalmente: uso a impressora Epson TX-115. Depois de fazer algumas atualizações sugeridas meu scanner não é mais reconhecido. Meu PC parece que está com outros problemas: as letras que aparecem ficam falhando (faltando partes), quando clico em fechar janela ele demora para fechar, ou diz que a janela não está respondendo. Antes ele desligava sozinho. Eu retirei um pente de memória, passei a borracha e ele parou de desligar. Alguém pode me dar uma orientação? Eu encontrei estes resultados no sources-list: Desde já agradeço a ajuda.
