Interface USB trava
Salve.
Em uma máquina com placa mãe Intel S875WP1 e Debian Sarge, a interface
USB trava após a retirada de um disposito de armazenamento (HD USB).
Um simples cat /proc/bus/usb/device trava, não conseguindo listar as
interfaces USB existentes.
Nem o kill -9 consegue matar o processo do cat.
Tenho que reiniciar a máquina para utilizar novamente a USB.
