Wireless BT Mouse Loses Connection

The wireless mouse connects to BlueTooth ok, but after a minute or so, it loses the connection. Problem comes from the power management setting on USB hub. Got this from a MS web link.

1. Click Start, click Run, type Devmgmt.msc, and then click OK. The Device Manager window opens.

5. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.
6. Repeat steps 3 through 6 for each USB Root Hub in the list.
7. On the Action menu, click Scan for hardware changes.
   Windows XP recognizes the new device.
