O joystick Usb detectado… e removido

Question

Eu tenho um problema estranho, onde meu joystick usb é detectado corretamente e, em seguida, bem removido pelo kernel.

saída dmesg ao inserir o conector usb:

No entanto, no syslog eu acho:

Eu aprecio o sistema de limpeza depois de si mesmo, mas eu gostaria de usá-lo um pouco entre: - (

A configuração funcionou anteriormente sem problemas, pensava que isso era durante a execução de 16.04 em vez de 17.04

Alguém tem uma sugestão de o que poderia estar dando errado ou qual caminho seguir para depurar esse problema?

EDITAR: Eu depurei um pouco mais e encontrei uma causa provável da minha miséria / mistério. Ao exportar o banco de dados do udev usando udevadm info -e , encontro o seguinte sobre o meu dispositivo:

No entanto, usbfs é um driver obsoleto que não é um módulo no meu sistema. Porque o driver não existe, não pode ser colocado na lista negra. Eu verifiquei se havia alguma menção a este driver nas regras do udev existentes no lib e etc, mas não há. Limpar o banco de dados usando udevadm info -c o remove da lista, mas ele está lá no momento em que eu repito para conectar o dispositivo.

Então, de onde vem esse usbfs e, mais importante, como removê-lo do hwdb?

    

Answer 1

Pensei que isso parece um pouco uma solução alternativa, vou postar minha solução (temporária?) de qualquer maneira, já que, por enquanto, ela corrige meu problema.

Eu uso usb_modeswitch para desanexar o driver não funcional e redefinir o usb:

% bl0ck_qu0te%

troque VID e PID pelos valores fornecidos por lsusb . Os números após o ID são VID:PID
