Actually, no.
You can't do it..  It's not the protocol, it's the power...

16-bit PCMCIA doesn't provide 5v, so there's not enough voltage for USB.
Cardbus has the 5V option, which is why you'll see cardbus PCMCIA cards...

There's one card that is 16 bit and could work. alexh has the info as AFAIK he helped develop it. It needs a driver though.
Found the thread you talked about.  The card is a "Oxsemi CFU950."

Looks like anyone who wants (is ABLE ) to write a drive could probably get that working.  But the odds there...  ;-(

Considering the power issues (especially drawing power from the Amiga, which can be picky about power draw), if you got it working, you'd want to attach it to a powered HUB, to keep the draw light.

I wonder if Giloo (who wrote ANAIS, the USB stack) would be interested in that?  He's probably got the best skill set for a driver with his understanding of Amiga USB.
Of course, someone would have to source some cards and get him one and the info alexh had.
