I am an Electronics student and want to do a BE project title-" USB to USB data transfer WITHOUT PC "
Can this project be feasible, if yes then what steps i should follow regarding selecting controller or specifications.
Kindly suggest some sites for detailed view on this project.
Is there any OS to be written for simply memory copying process.
Thank you

Every USB transfer is between a host and a device. The host can be a PC or an embedded system. For information about embedded systems that can function as USB hosts, see:

Yes...you can have such a device.
I have already implemented the embedded device which transfers data between USB devices without the intervention of PC/Laptop/Palmtop/Mobile Phone etc...
 and it works perfect Smiley

It sounds to me that you've developed a host that acts as a master to specific devices.  As Arvie wrote in his post, we'd be quite curious to hear more details about your "device" - especially what USB devices it works with.

Isn't this just exactly what "USB On The Go" is about?

I have to admit, I haven't noticed a single product featuring USB OTG, but I suspect at least one exists.

Yes, an On-The-Go device can function as a device and as a host that can access a limited number of peripherals.
