USB 2.0 high-speed devices are recognized as full-speed after you hibernate and then resume a computer that is running Windows Vista or Windows Server 2008

This article has been archived. It is offered "as is" and will no longer be updated.
Assume you connect a high-speed USB 2.0 device to a computer that is running Windows Vista or Windows Server 2008. After you put the computer into hibernation and then resume the computer, the USB 2.0 device is recognized incorrectly as a full-speed device instead of a high-speed device. Therefore, the transmission speed over the USB connection is significantly reduced.

This problem occurs occasionally.
A race condition in the host controller startup sequence causes a short reset signal that a USB 2.0 device may interpret incorrectly. This behavior causes the high-speed handshake for the device to fail. Therefore, the device stops trying to make a high-speed connection.
