That's probably the case. you might try other cards, to verify that
they work. but i'll note that e.g. on my machines that i mentioned
earlier, i was completely unable to find more than 32KB in one
contiguous area that could reliably be used for PCMCIA memory.

I've only seen mention of a couple of these on the web, and invariably
they've all been back-accessable, so they've not been interestnig to

I've never seen a CardBus adapter that sits on USB. I've seen some
pcmcia storage / cf / smart media adapters, which might work with
umass, but the one that i didn't present a reasonable device class
value. (it was the siig. *sigh*)

This is the joy of ISA. It'll be good when ISA is dead.
