Problems when installing the Siemens PLC S7-300USB/MPI programming cable driver

Installation of Siemens PLC S7-300 USB/MPI programming cable When driving, the driver is pre-installed successfully! Plug in the device and select Auto Install in the “Found New Hardware Wizard” dialog box that pops up, ignoring the driver digital signature warning. I clicked (OK), after plugging in the USB cable, the SIMATIC PC Adapter USB still displays a yellow question mark in the device manager and cannot be installed.

 

Plug the cable first, then open the location of the driver to install, pay attention, which usB port is installed, you need to restart, close the anti-virus software
