okay. i got a usb mass storage device for my laptop and it is plugged into my usb1.1. it works fine...but i wanted a 2.0 speed. so i bought a combo card with 2 usb2.0 ports and one firewire port. i also have an ipod. so...when i plug my mass storage device into the usb2.0 port, or my ipod into the firewire port....it recognized them on my "safely remove harddrive" thingy...but it doesn't do anything. like, the ipod won't update on itunes, the z: drive of my storage device won't open..but it still recognizes everything. so i gave up on fixing it and put my old firewire card back into the driver...and i plugged my ipod in, and it won't work either! its the same thing, it recognized it, but it still won't do anything.
i think this is a computer problem...maybe i accidently deactivated something. can anyone help me please!!!! i need music and stuff, i am about to kill myself. thank you.

ps. i have a gateway pc with windows xp.
