I must be the odd one out. The PCMCIA to USB2.0 card came and was installed on the laptop. I plugged the camera in, but got nothing, just a black screen on "My Computer" Funnily enough I plugged it in the old USB 1 port(s) and got a picture on "My Computer".
Mach3, however, still failed on USB1 port, and now fails on the USB2 port (which is not suprising).
I found an upgrade on Microsoft for the PCMCIA card to USB, but that failed as well, saying that it could not find some information it needed.
I will keep trying when I get some more time.
