How To Use PID code to identify/Download Drivers for The Webcam
There 2 ways you can identify your webcam device and download the proper drivers.
1. By downloading from the manufacture download site.
Example you have an Asus A42JC, so we go to the download site and we will see lots of webcam driver listed, and we need to select one base on the PID code that matches the PID code displayed on the download site.
2. If you manufacturer does not list out the hardware ID or PID code for your webcam, we just need to Google the hardware ID to find out the right webcam driver. Example if you have an Acer 1810T and on the download site there are 3 drivers listed:
So to choose the right driver first we must obtain the PID code.
If Hardware ID is:
USB\VID_04F2&PID_B175&REV_1357&MI_00
So the PID Code is : PID_B175
Now if we Google the PID code the result would be:
From the search result the right webcam driver is chicony. If you have problem do let me know.
