The dongle is lost, is there any way to save it?
The dongle is used by software vendors to protect the copyright of the software. Generally, a set of software is bound to a dongle. The software vendor will write some important information into the dongle. If the software cannot find this part of the content, it cannot be used normally. If it is lost, it can only be used. It is to find a software company to replenish one, or you can ask the software company about the dongle model, buy one yourself and let the software write down the dog, but because the software company is not good at judging whether you really lost it, so you have to Negotiate with him yourself.
