Eu tenho um dispositivo USB com defeito que causa o seguinte erro na inicialização:
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-3: device not accepting address 6, error -62
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-3: device not accepting address 6, error -62
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-3: device not accepting address 6, error -62
usb usb2-port3: unable to enumerate USB device
Eu tenho que esperar o tempo limite antes que eu possa inserir minha senha dm-crypt para continuar o processo de inicialização.
Existe uma maneira de desativar esse dispositivo para que o kernel não se importe com isso? Eu não posso desconectar porque está embutido. Eu não tenho nada que eu use no usb2 também, então não há problema em desabilitar todo o hub. Eu tentei colocar blacklist cat /sys/bus/usb/devices/usb2/2-2/2-2:1.0/modalias e cat /sys/bus/usb/devices/usb2/2-0:1.0/modalias (todos os modalias que eu posso encontrar em usb2), mas isso não funcionou.
