Hi, Has anyone got any experience with systems based on the nt1003 chip, particularly the Belkin USBView II frame grabber? There is a driver for it at http://aeinnovations.com/downloads/USBvision/ but I cannot get it to work: something is going wrong when the application opens /dev/video0, and no image is transferred. I am using usbvision-0.3.3-test1 on a 2.4.7 kernel (I tried 2.4.18 initially, but stepped back to 2.4.7 in case it was a kernel version problem). Apart from the kernel, the installation is standard Red Hat 7.2. I have attached the messages logged to /var/log/messages and the console output of the grabber application, which is webcam from xawtv 3.54.
Alternatively, can anybody suggest another usb video grabber that I could use? Thanks, Chris.
