You may experience one of the following symptoms:
When you start a Microsoft Windows XP-based computer that uses a universal serial bus (USB) mouse that is connected to a USB 2.0 hub, the USB mouse is not detected.
When you plug a USB mouse into a USB 2.0 hub that is connected to a Windows XP-based computer, the USB mouse is not detected.
This behavior may occur because of a timing issue that prevents a USB mouse from being detected by Windows XP.
To work around this behavior, unplug the USB mouse from the USB hub, and then plug the mouse into the hub again. If the mouse is still not detected, restart your Windows XP-based computer.
If the USB mouse is still not detected and if you do not require the USB hub to connect other USB devices, plug the USB mouse directly into the computer.
If the USB mouse is still not detected, verify that the USB hub driver is installed and running correctly. To do this, follow these steps:
Click Start, click Run, type Devmgmt.msc, and then click OK.
In Device Manager, expand Universal Serial Bus controllers. If the USB hub driver is not working correctly, a yellow circle that contains an exclamation mark appears on the device name.
Right-click USB Root Hub, and then click Properties.
On the General tab, verify that a "This device is working properly" message exists in the Device status area.
Note Some earlier motherboard versions do not support USB 2.0. An update that adds support for USB 2.0 may be available for your motherboard BIOS. Contact the manufacturer of your motherboard for more information about BIOS updates.
