I have been bisecting around the 3.13 and 3.14 kernel releases:
The 3.13.11 fails, but far less often than the 3.13.0, and with a dmesg trace
that indicates an attempt to trace a USB issue of this kind. See dmesg_3_13_7:
[ 20.158116] [ cut here ]
[ 20.158126] WARNING:
Malaise, the next step is to fully reverse commit bisect from kernel
3.13 to 3.17.8 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,

release. Could you please
Fixed in 3.17.8-031708
