Thanks guys, appreciate the help and ideas, have checked the device manager and made sure all power saving features for usb hubs are off, couldn't find any power management issues related to usb settings in the bios (just enabled or disabled), and have checked my power options in windows and made sure that selective usb sleep is off, strange behaviour when I open usbtree viewer, the hub that is the issue, (regardless of location), frequently, shows red symbol on it and then goes beserk trying to connect...this even shows in event ghost
