i have a pavilion dv2353ea HP laptop and one of the usb ports has power to it but will not work on my desktop (the mouse wheel on top light is on but the one underneath is not on)but works fine in the second port
on both usb ports my external HDD work every so often in the first port where the mouse doesnt work the HDD is worse then the second port with the second port i can keep trying to import and export files but it will turn off and on again but work after a while. (the same happens with the power issue all lights on HDD but desktop it comes on and off)
