Vincenzo - I have the exact same USB 3.0 controller: 0d:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04)
... on this Thinkpad 420s, and I have no issues using the B100. Like Nick said, can you provide the output of: $ sudo lspci -v $ uname -a Also, without making any changes, if you plug the B100 into a USB2.0 port, it works fine?
