Consider the following scenario:
* You have a computer that is running Windows 7 or Windows Server 2008 R2.
* The computer has an NVIDIA USB Enhanced Host Controller Interface (EHCI) chipset.
* The computer has at least 4GB of RAM.
* You try to copy data from the computer to an external USB storage device.
In this scenario, either of the following issues occurs:
* The computer stops responding.
* The copy operation stops.
Notes
* This issue may also occur when you are using USB devices other than storage devices.
* This issue may also occur if you perform other input/output (I/O) operations on the USB storage device. In this situation, the I/O operations fail.
