hub_port_status failed (err = -110)

Hello,

on multiple machine, when reading data from USB port CDC driver (actually using arduino uno, arduino due, stm32f3-discovery) i often get a

hub 1-3:1.0: hub_port_status failed (err = -110)

now if i try to run lsusb and usb-devices freeze, and aslo if i shiutdown the PC it will hung ouputting on loop "hub 1-3:1.0: hub_port_status failed (err = -110)", a hard reser/shutdown is required.
