Open up your “Device manager” on your computer and expand “Human Interface Devices”.
Note which devices are in there and plug the USB-cardreader into a free USB-port on your computer.
Now there will be a new device under “Human Interface Devices”, rightclick that device and choose “Properties”.
Now choose “Details”-tab and “Hardware ID´s” in the dropdown-menu.
Now you see the VID and the PID, which here are: VID: 04D8 and PID: FE86. Remember when putting in VID and PID to use 0x in front of the value.
