Hi.
I also thought about using VUSB to implement an USB mass storage device on an AVR.
The specific classes are called MSC - and they all utilize bulk-transfer mode.
Since VUSB can not provide bulk (only low-speed USB) and alternatively interrupt transfer is not always accepted by USB-hosts it is not possible to implement MSC on VUSB. Not without implementing a seperate driver for the host and using a complete other way of transfering data.
