Até alguns dias atrás, minhas unidades USB funcionavam bem. Eu não tenho certeza do que mudou entre então e agora.
Tanto a unidade flash USB como o disco rígido externo USB funcionam bem em outra máquina Windows, mas no Xubuntu 15.04 aparecem no dmesg sem problemas. Um deles aparece em lsusb (o pen drive USB) e ambos não aparecem no fdisk ou no gparted.
saída dmesg para a unidade flash USB:
[ 6444.808406] usb 1-1.1: new high-speed USB device number 10 using xhci_hcd
[ 6444.897204] usb 1-1.1: New USB device found, idVendor=0781, idProduct=556c

Alguma idéia?
