There's this school software on a USB drive. It only runs, when the stick they gave is plugged in. Cloning the drive with dd command didn't work. I'm guessing it checks the hardware ID of the flash drive. Is there any way to change drives information? I guess not, but is it possible to create a virtual flash drive with exactly same hardware id and all other read-only information that the software is most probably checking.

EDIT: The paper math books we have dont' have answers. So when I'm doing homework I have no idea if did it right. The electronic version does have the answers. The publisher didn't put them into paper version because of simple reason - money. They would have to republish the book if some answers are found to be wrong. So I feel no shame trying to pirate that software, because publishers are ruining our math education.
