USB Microcontroller Question

I am just getting up to speed on using USB in an embedded
environment.  What I am wanting to do is to use one of the
available microcontrollers (AVR,PIC,etc) in a USB HOST mode.
 In particular, I desire to interface a USB mouse to
an embedded project.  Is this feasible with the
microcontrollers available?  I could use some advise in
regards to this issue.  Thanks
Jim

The original poster asked for USB *HOST* mode.

Microchip makes several USB OTG devices.

Look at the Vinculum VNC1 - I think it can be used for things like mice and printers in addition to
its filesytem functionality

Microchip has a few 16 & 32 bit chips which support USB host mode. 

Check out AN1141, for example.
