Hmm, you're the second person to report an issue with a host dying.

Please try a 3.13-rc7 kernel after running `git revert 35773dac5f86`.

Which patch are you referring to?

Was the ReadyNAS 102 with the Fresco Logic host running 3.13.0-rc7 as
well?

Those messages are normal.  It just means the device transferred less
data than the host asked for, which is part of normal USB operation.

Does the dock work despite the messages?

Please send me the output of `sudo lspci -vvv -n` for the ReadyNAS 102
Fresco Logic host.
