"PC Card" is a friendlier name for the physical format.
"PCMCIA" is 16-bit ISA.
"CardBus" is 32-bit PCI.

I don't think I've EVER seen an ISA-bus USB controller, regardless of 
the physical format of the card. And I know for a fact that I've never 
seen an SBUS USB controller.

If you're just wanting to use more modern removable media with the 
system, maybe try looking into a "USB floppy emulator" or something like 
a SCSI2SD card ( http://shop.codesrc.com/ )
