Hi all, I am having USB 2.0 ports at the back of my computer. When i connect my MP3 player to it, the player displays "Insufficient power" but when connected to my friend's PC it works fine. I guess there is some problem with my USB port output. I heard that the output from USB 2.0 port will be 500mA. Is there any way i can check the output power of my USB port? Is it possible to have a new Port for my computer? Please help me...

You may need a new USB card to come up to the 2.0 version. Is your computer old?
Here's a card that will probably work but you'll need to check your PC specs first.

This Y cable might be a better choice. It allows you to take the power of 2 USB sockets from the back of your computer and harness that in to one.
