USB and imate problem !?

ok i have imate jam and i have been trying to connect it to my PC with MS ActiveSync but i couldn’t the windows will see the device and it will try to connect but after connecting it will disconnect soo fast.

and when i use it with my laptop it will connect soo smooth.

so i tried to search about this problem and i heard that some old VIA mobo have problem with it.

my mobo is GA7VAXP with VIA KT400 chepset.

so i was just wondering can i go and buy USB PCI card and it will work ! ? i mean buying seprated PCI card will avoid the conflict with my MOBO USB ?

thanks …
