Eu uso uma placa PCIe USB 3.0 externa. Ele costumava funcionar como um encanto em 13.10. Mas desde que a atualização para o 14.04 hot-plug parece não funcionar mais. Ela costumava trabalhar antes.
Somente quando esta placa está conectada, ela está funcionando. dmesg mostra: 03: 00.0 Controlador USB: NEC Corporation Controlador host USB 3.0 uPD720200 (rev 03)
Quando conectado durante a operação, recebo apenas uma mensagem de que ocorreu um evento hot-plug. Além disso, nada acontece.
Alguma ideia do porquê?
Eu tenho pesquisado para cima e para baixo na pasta / var / log.
Parece-me que o kernel não reconhece o cartão durante o hot-plug

Quando o cartão foi conectado no momento da inicialização, ele aparece no lspci. Quando eu desconecto, então, ainda está lá!
