About a year ago I couldn't find any.  Manufacturers seemed to assume
that the host would require a larger OS & application framework (like
WinCE and Linux) to support the USB stack, and it's hard to fit this
into on-chip FLASH.

The closest I found was an ATMEL AT91RM9200.  It has a ROM that can be
mask programmed, and it can boot from an external serial device.  If you
paired your code down to hard support for a single device, this could
give you a *reasonably* small system footprint.
