A few days ago, the camera at my home was accidentally broken. So I went to the mall and bought a driverless camera, the kind that doesn't require installing any driver software - there wasn't even a driver CD in the packaging. It cost me 99 RMB, which made me quite heartbroken.
What happened next was even worse. After plugging the camera's USB interface, I tried to have a video chat with a QQ friend but couldn't see anything on the screen—just a pitch-black void. I realized I was encountering the black screen issue with a driverless camera. After much deliberation, I searched extensively on GOOGLE and Baidu, and finally found a patch program for the black screen issue of driverless cameras. I know many of my peers must be facing the same situation as me, so based on my experience, everyone should give this patch a try. According to netizens' feedback, it works pretty well. The patch is in the attachment; you can download it directly. (It seems to only work on the XP system.)
