Atmel makes USB OTG (host and device capable) microcontrollers too, and
the tools are much easier to use.  There's a guy named Dean Camera who
has written a much better library for driving these called "LUFA" and it
includes host demos for keyboard, mouse, CDC and others.  "CDC" is what
a standard USB serial port is.  There's a $30 "USB KEY" devboard with an
AT90USB1287 that is host capable which you could try this on.  I believe
the demo just connects the standard TTL serial port on the AVR to the
USB serial, which is exactly what you probably want...
