A few companies made them, though the two I'm familiar with are Adaptec and Xircom.
IIRC, neither have drivers for Mac OS X, just 9.x (as well as Windows 9x through XP). I have both, but have only ever really used the Adaptec and that was with a Jaz drive under XP. I can say that it worked pretty well for that application, though. As I recall, the adapter loaded firmware upon initial plugin, reset, and then presented the drives as a standard USB block device.
Ironically, I think I saw a NIB Adaptec in a closet at $WORK, the other day.
