VID and PID are numbers that identify the manufacturer and model of a USB device. Here's how you can find the VID and PID of a USB device in Device Manager:
- Open Device Manager
- Double click on the unknown device.
- Click on the "Details" tab.
- From the "Property" dropdown menu, select "Hardware Ids"
The "Value" field will now display the VID and PID. For example:
USB\VID_2341&PID_0042&REV_0001
USB\VID_2341&PID_0042
We can see that the VID of this device is 2341 (that's Arduino's VID) and the PID is 0042 (that's the PID of the Arduino/Genuino Mega).
