USB Power

Hi everyone, I'd like to know if it's possible to keep a USB port 'on' or constantly powered. I'd like to use this to charge my mobile phone through a usb cable while the computer is off.
If it helps, my OS is Windows XP and.. I have a Motorola Razr(spell?)
Thanks for your time!

PS It's my first post. :D

Some motherboards have jumpers to select whether USB ports are powered by 5VDC (on when PC is on) or by 5VSB (standby power, always on).
