Hi,
it's not a hardware-problem - it's a windows feature
- (and it really is one !) - please try this:
To prevent a USB mouse from waking your PC
1.
Open Device Manager by clicking the Start button, clicking Control
Panel, clicking System and Maintenance, and then clicking Device
Manager.
2. In the list of device categories, expand Mice and other pointing devices.
3. Right-click the entry for the USB mouse, and then click Properties.
4. On the Power Management tab, clear the Allow this device to wake the computer check box.
5. Click OK.
Don't forget to do this with your mouse + keyboard !
