USB devices do not work after you disconnect and then reconnect a USB hub from a computer that is running Windows XP


When you disconnect a USB hub from a Windows XP-based computer, and then you reconnect the USB hub, USB devices that are connected to the USB hub do not work. Additionally, when you connect additional USB devices to the USB hub, the additional devices are not detected, and they do not work. This problem may occur only occasionally.

Note The USB hub may be integrated into a docking station or into a port replicator. Therefore, you may also experience this problem when you disconnect a portable Windows XP-based computer from a docking station or from a port replicator, and then you reconnect the computer. When you reconnect the computer, USB devices that are connected to the docking station or to the port replicator do not work.
