Usb 2.0 Install In G4 Agp, Ipod Mini Not Recocognized



I bought this MACSENSE USB 2.0 card ( 4 slots respectively ) which I connect in my G4 AGP PMac. It shows up in System Profile BUT connected to my iPod, the iPod goes to "Do not disconnect" sign or just the ipod menu shows.... and it doesn't mount onto the Desktop. itunes does not recognize it.
10.3.9 is running.
all upto date.
I thought it would be just plug and play or is the firewire connection the way to go.
What are the steps for the PCI upgrade card. Something I need to do?
Any suggestions? Problem with the card? Problem with my MBoard or just unlucky?
