How do you rip dongs off of a device onto your computer?

Your question is puzzling. Perhaps you are asking about "dongles".

Many software applications use hardware "dongles" to prevent multiple copies from being used when someone purchases a single copy of software.

You can read a little more about dongles at:

Since the purpose of the dongle is to prevent software piracy, it's presence will be necessary for the software to run. At runtime the application sends out a query to the dongle and expects a specific response. If the response is not received, the software will refuse to function properly, if at all.
