A placa serial PCI não fala no sistema Linux?

Question

Estou executando o Mageia Linux e tenho uma placa PCI com 2 portas seriais e minha placa-mãe (ASUS H81M-A) não possui nenhuma porta serial onboard. A placa PCI é fabricada pela WCH parece. Eu tentei instalar o driver Linux que veio com a placa, mas meu sistema encontrou um monte de erros neles e parou de instalar o driver. Meu cartão se parece com isso e ele tem CH3825SP @ 1107 direito sobre ele.

Então,comeceiaprocurarajudaon-lineeencontreialgumasinformaçõesparafazeroseguinte.

Emseguida,executeiestecomandosudosetserial/dev/ttyS0uart16550AparadefiniraPortattyS0naplacaPCI.Deacordocomaspostagensdoblog( Serial-Port-Work-Linux e eletrônicos FAQ ) que encontrei on-line, isso tudo eu tenho que fazer para usar minha placa PCI serial. No entanto, isso não funciona. Depois que eu executar o comando setserial , meu programa não poderá acessar o ttyS0 . Eu não sei o que estou fazendo ou como fazer isso funcionar. Qualquer sugestão ou ajuda será muito apreciada.

UPDATE Aqui está o dmesg para PCI. Desculpe se é muito longo. :)

Answer 1

Parece que o suporte para o seu cartão foi adicionado recentemente neste ano . Se o kernel é novo o suficiente, você deve verificar se o módulo do kernel está carregado com

lsmod

se não, você deve carregá-lo com

sudo modprobe serial_cs
