New Laptop, 2 usbs, only one works with mouse??

[Shoot59]

This might be a dumb question, but I just bought a new laptop (hp pavillion running vista) and a logitech cordless mouse. The laptop has 2 usb inputs, one on the left side of comp, one on the right. The mouse only works in one of them (the left one) but I want to plug the little usb wireless piece into the usb port on the right. The usb on the right works for jump drives, just not the mouse. Any ideas why? Thanks in advance...
