Same issue on Win7 x64. Described it on different thread also.
Played with several Intel USB3.0 drivers - no success.
Updated USB hub with firmware from Lenovo 2012 - no success.
Used official Lenovo drivers (little bit older than those you can get here) - no success.
Not related with any attached devices - even with none connected it is same behaviour.
On first run it works for ~20 minutes. Then looping unrecognized & reconnection.
Is my dock defective?
Will do now the debugging steps and supply you the results.
