1. The parallel port encryption dog needs to be installed with driver, and there is no parallel port encryption lock without driver; The reason why you think it is driveless is that the software manufacturer packaged the driver into the software package. You have installed the driver of encryption lock when installing the software;
2. It may be connected to the encryption lock through the print card, and the power supply voltage is insufficient, so that the encryption lock cannot be recognized. If possible, it is recommended to replace a print card (i.e. the card converted to parallel port) and try it;
3. If not, it is recommended to contact the software manufacturer and recommend that it replace the USB dongle. Now the parallel port lock is almost not used. It is an antique product ~ hehe
