USB2.0 Flash Controller for Microcontroller project - 2bluesc - 08:36 22-07-08

I'm building a data logger with a microcontroller and logging to a microSD
card over time and then want to be able to copy it off fast over USB with a
USB 2.0 Flash controller like those found in PC flash card readers.  I
stumbled across this webpage @
http://www.hjreggel.net/cardspeed/info-controller.html , but am unable to
find any places that sell these controllers in small quantities (ie <10).

Anybody have any experience with tracking down a source for these chips?

SMSC chips are relatively easy to find, if I remember correctly even
Digikey and Mouser have some of the USB22xx family chips.
