Today I ran into a problem: I need Windows XP driver for the Colorvis Z1 webcam. As usual, I have my belief on Google and because I'm using Google Chrome, I typed into Chrome's Omnibox: "windows xp driver colorvis z1", I clicked a few links but nothing works! Most of the links are from search engines or software portal sites. They did their job pretty well and I believe mis-clicks from people like me generate quite much revenue for them despite the fact that their site is useless!
I was going to give up but then I got an idea. I went directly to Google Vietnam and typed this query: "driver colorvis". Actually, a few suggestions came up and I selected "driver colorvis 6 mat" (in English: "driver colorvis 6 eyes") and I got this site in the second position. I downloaded the driver and it works!
So, in conclusion: After ~100MB downloaded driver from international sources, my webcam is still useless but after the first try with 25MB downloaded, it's working like charm now!
This is one of many aspects which a Local Search Engine (version) will beat an International Search Engine (version). Have to go playing with the webcam now. Haha
