How to simulate a USB drive

Question

Hi all,

Is it possible to simulate a USB drive with software only? I mean, for example, to expose a local memory space to the OS so the device manager will recognize it as a USB device. I'm not familiar with hardware implementation, but I'm sure that it is possible somehow to emulate the USB protocol.

I began with this book - USB Design By Example.

Can anyone please give me additional references to begin with?

Thank in advance!

You need to create a set of kernel-mode drivers that will do the job (block device driver and some supplementary code). Alternatively you can check our virtual storage products that let you create a virtual disk and expose it to the system.
