The USB device could be drawing more current than the USB port can supply or the USB port may be faulty.
Get a powered USB hub and plug it into your computer's USB port and then plug the USB devices into the powered USB hub.
umm, usually you can't. your board is probably feeding too much current/voltage to the usb ports or someone shoved a paperclip into the port and shorted it out (frying the power supply to the usb ports) in any case, you will probably need a new motherboard or power supply.
Try this to find out which one of your components has an issue. Turn off your machine then unplug all of your USB cables. Turn your machine back on and plug in one of your USB cables. Verify the component you just plugged in works correctly and if it does plug in another cable and verify that component is working. Continue these steps until you have the one component that displays the error you have seen. That component is most likely the cause of your issue and should be replaced.
Does your External drive have a seperate power supply? Or does it get its power through the USB port.
If it gets its power from the USB port then by adding a hub you are essentially dividing the amount of power supplied by the number of ports extended.
One possible solution that could solve that situation would be to get what is called a powered hub. Which is exactly as the name suggests. The Hub has an external power supply so that it can provide even power to all of the ports.
I hope this helps
If not please post an update and I can try to find a better solution
