SYMPTOMS

If you dock your laptop computer in a docking station that contains a Universal Serial Bus (USB) controller and the computer is suspended (put into Standby mode), when you undock the laptop and attempt to resume operation, one of the following symptoms may occur:

The computer may stop responding (hang) at a black screen, and a hard reset or power off and power on may be required.
The computer may spontaneously restart.

CAUSE

This behavior can occur for the following reasons:

If the USB controller in the dock is an OpenHCI type controller (made by a manufacturer other than Intel) and other PCI devices are sharing the same Interrupt Request (IRQ) number. When the OpenHCI controller hardware is no longer present, the OpenHCI controller driver (Openhci.sys) may hang while processing an interrupt during resume.
When the USB hub driver (Usbhub.sys) attempts to determine the status of the USB hub during resume when the USB hub hardware is no longer present, the Openhci.sys driver does not correctly detect this condition and the USB hub driver becomes stuck in an endless loop.
