disconnecting / reconnecting - windows has stopped this device...

[ITDrone]

Hello,

Lenovo Helix (Win 8.0) + USB 3.0 Dock (v. 7.5 M0)

The dock may work fine for weeks at a time or just a single day, then randomly it will start disconnecting and reconnecting every 5 seconds. The only fix is to unplug the dock, go into the device manager (where it's showing up as "Unknown device") and uninstall the dock, reboot, and plug it back in.

Device Manager says:
Windows has stopped this device because it has reported problems. (Code 43)

Any ideas?
