USB Overloaded

You occasionally need to check the power demands on your ports. For this you have to go through the Device Manager. If you use Windows XP or 2000, right click on your My Computer icon and select Properties. Then choose Hardware, Device Manager. It must be born in mind that the maximum is 500mA.

Within the Device Manager box, double click on Universal Serial Bus controllers (it is usually the very last item on the list). Next, double click on the first line that says USB Root Hub. There will be multiples of those, but click on the first one listed, or continue through the list until one displays the items when you select the Power tab.

Under the Attached Devices area, you will find a list of all the devices you have running through your ports at the moment. You will also be able to view each one's power requirements (in milliamps). As mentioned above, a port can handle up to 500mA, so if one of your root hubs is close to that 500 mark, you need to switch around some of your devices to other root hubs so that everything isn't all filling up on one.

You can also connect another hub to your PC if you have an available port. There are hubs available out there today that can turn one port into four or even more.
