USB Peripherals Potentially Dangerous
You may have seen or used one of those ‘USB toys’ such as a fan or a rocket, but did you realize that they can be potentially dangerous to your USB ports.
A USB peripheral pretty much just sources power from your USB port and in some cases it sources way too much power which will lead to your USB port burning out and becoming useless. With the amount of these ‘toy’ being used around the world at the moment its amazing that we haven’t heard more about the potential danger of these things.
If you do run a USB peripheral you can check exactly how much power it is running in both Windows XP and Vista. To do this you must;
- Open your Control Panel
- Click Device Manager
- Go down to Universal Serial Bus Controllers and open it
- Right click on the first ‘USB Root Hub’ and select properties
- Click the Power tab
- Here you will see the power being used in your USB ports
You will see your peripheral under attached devices and the power it is using. You will also see at the top of the tab the total power available for your hubs.
Basically all you need to check is that your USB peripherals are not going close to or exseeding your total power available. If this is happening you must take out your USB peripheral immediately and find an alternate power source otherwise you will burn out your USB hubs.
