USB Powers up 30 secs after powering down computer

  PA28 19:57 04 Oct 04

Help. Have installed new mobo (Gigabyte GA-7N400) and AMD3200 after found earlier problems caused by a faulty mobo. Clean install of XP with SP2 while I was at it. All working fine except that the USB hub powers itself back up 30 seconds after switching the computer off. All LEDs come alive - it takes its' power solely from the PC.

Have disabled everything I can find in BIOS and Windows Power Mangement settings, but still it happens. The only way to kill it appears to be pulling the plug (either the USB or the mains!!).

Any ideas please?
