I recently upgraded 14.10 and this bug still persists. Its a Lenovo Thinkpad x230t with an Ultrabase series 3.
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date GCET99WW (2.59 ) 05/28/2014 $ uname -r 3.16.0-23-generic Package is: 3.16.0.23.24 Just to confirm here is the relevent parts of my dmesg after I run into this issue: [143413.038373] usb 3-3.4: ep 0x81 - rounding interval to 64 microframes, ep desc says 80 microframes [143413.038379] usb 3-3.4: ep 0x82 - rounding interval to 64 microframes, ep desc says 80 microframes [143413.038387] xhci_hcd 0000:00:14.0: Not enough bandwidth on HS bus for newly activated TT.
