Does that mean that usb transfer would be too slow
I don´t ask this with the intention of hooking up a 52x cdrewriter, anything slower will also be nice. Is it the USB 2.0 that is too fast or is it the card itself
Would a USB 1.1 card be better 
Cardbus is interfaced differently than PCMCIA, so it just won't work even if you did have the drivers.
Also, the A1200's PCMCIA port won't feed a 52x CD-RW at max speed. USB 1.1 won't cut it either - it's more like 4x maximum.
