microcontroller host using V-USB

Hey, I have a project where an atmega8/16/32 or any microcontroller really, transfers data between two usb devices (in my case, pen drives). I do not want to use a host controller, that's done. I thought of implementing the usb protocol myself, but soon realized I may have overestimated my abilities :/
So can the V-USB be used for a microcontroller host ? If you guys have any alternative ideas, please let me know.
Thanks !

Been there done that. I mean overestimating my abilities. The thing is, nothing would get invented if we weren't naive enough to try something impossible.

There are probably AVR, PIC, and ARM MCU's which have a built in USB Host (or OTG which is designed more for removal of the classic idea of Host/Device abstraction). I would take a look at some of the ARM Cortex MCUs that are starting to become available really cheap. Those which have the USB Host implemented in hardware could really simplify your task.
