how to make a usb drive be recognised as a CD/DVD drive?

is there any way i could get a USB drive be recognised as a CD/DVD rom?
or a way to make a iso run from a USB drive when inserted into a computer?
thanks

Well, you can use Alcohol 52% to make an ISO to run on a computer.It can run off of a flashdrive as well.http://www.free-downloads.net/programs/Alcohol_52__Free_Edition

you can put an iso on a flash drive and mount it with daemon tools

no you cannot change the device type.

There should be away to imitate those USB CD/DVD drives using an external HDD and run a script with autorun. You might need to find/write a script that uses a driver to do this.

hard disks can have autoruns but there needs to be a registry change on the computer to actually use them.

it would be much easier to mount the iso from the usb drive...
Unless of course you wanted to make it a bootable disk, then you would have to use some program that I can't remember.
