THE SYSTEM REQUIRES THAT I UNPLUG ANY USB DEVICE CONNECTED TO IT BEFORE HYBERNATION OR SHUT DOWN, FAILING WHICH, I'LL ONLY GET A BLANK SCREEN AFTER LOG ON, WITH ALL INPUT DEVICES NOT RESPONDING.
I TRIED TO ADJUST THE BIOS SETTINGS BUT, IT NEVER WORKED, I DONT SUPPOSE IT COULD BE OUT-DATED BIOS AS THE VERSION ON MY SYSTEM WAS RELEASED ON JANUARY 2005.

Re: USB HUB FAILURE
My advice would be to not use hibernation, there are too many posts with people putting their pc into hibernation and not able to get it to wake up again, partly because of hardware issues relating to usb power ups afterwards.
I would rather use the log off or switch off as hibernation only comes into use for conserving battery power in notebooks.
also do not attempt to update the bios if there are no problems as you may render your pc useless

There are quite a few steps to check in this problem. If you are using windows you can check the device manager, make sure there are no errors in the drivers or that the devices aren't disabled. They could also be turned off due to power saving on the PCs behalf, which can again be checked by device manager, USB root hub, right click and select properties, under the advanced tab I think it is there is a checkbox to allow the PC to turn off USB to save power, make sure it isn't selected. Failing that you may need to check the BIOS to ensure USB is enabled. Have you tried more than one port and is it a physical port on the PC or a USB hub plugged into the PC?
Do any other devices work on any of your USB ports on the desktops? Does the memory stick work with a port that works for another device?
If all of the ports fail, check the Device Manager (for Windows OS) - you may have a driver issue. This is reached through the Control Panel (under Hardware or System). The exact titles will depend on the version of the OS.
When you scroll through the list to the USB controllers, look for a triangle with a red x or a yellow triangle. The right click (or double-left click) and try to update your driver or roll back the driver to an older version that worked.
If only a few ports fail, then are you dealing with the front ports or the rear ports? If the front ports (case), then you might want to check if the header cable is fully connected to both the case and the motherboard. This requires opening the case with the appropriate care.
Unfortunately, some new USB devices pull too much power through the port and can burn them out. (Those that charge on the computer are the most likely culprit.) If you have a few working ports, get a USB hub that is self-powered. (Get a good one or only use the AC adapter when there are more than 4 devices connected to the hub.)
this message popped up because one of the device which you connected to the usb of the pc was overdrawing current i.e more than 5V DC. Hence, the built in system security gave this message and will shut down your computer in 15 seconds. In order to avoid this message first remove all the usb items connected to it and then connect one by one and detect the faulty one and replace.
A USB device is drawing too much power so the system crashes. Remove all devices attached to USB and try again. If it's the same then remove all external USB ports - the ones connected with wires to the motherboard. If it's the same then there's a short in the motherboard - unfixable, replace it with a new one.
If you see something wrong with the device everytime you plug in something to the USB hub doesn't necessarily mean that the hub is defective but it may actually mean that the device may not be receiving enough power to make it work. As we all know USB a device that may or may not have its own power but at least we know its working when by check the light indicator on the device or checking in device manager and that is an indication that it may or may not work with a hub and may need to be directly connected. If device you hook up is working with direct connection try isolating it by hooking it up from one port on the hub to the other this may actually help you out determining if there is defective port on the hub otherwise you got a lemon any may to return the product as well consult with them which product have they tested that actually worked with it.
