I have Windows 98 SE with an ASUS mobo and two USB ports on the back.

Several people have reported problems with certain ASUS P2B motherboards - particularly older ones. It turns out that USB does not work in Windows 98 with any USB device on some of these boards - not just the empeg-car.

One user did manage to make USB work with Linux (though not with the empeg-car) so it may not be a purely hardware issue.

I may not be speaking on behalf of empeg above :-)
