Hello,
My name is Daniel Djamaludin and I am doing a thesis at university which requires the
USB drivers for Linux to be backported to the Linux 2.0.38 kernel. The 2.0 kernel is
required since it is to be placed in an embedded systems environment. The aim is to
use an ov511 camera with USB support to be run by Linux 2.0.38.
I received very useful advice from Alan Cox and Vojtech Pavlik earlier this year on
where to start. I have almost completed the backport, which has largely been based on
Alessandro Rubini's code. The 2.0 USB drivers can initialise and detect the ov511
camera. However, when vidcat tries to capture an image, only a blank white image is
produced. I have placed a liberal amount of printk's in the drivers and compared the
output between the 2.2.14 and 2.0.38 kernels. As of yet I haven't been able to detect
any significant differences.
I have included the backport header file which resides in include/linux/ for perusal
if anyone can help me. I am not a crash hot device driver writer (ie. not very
familiar with shedules and interrupts etc), but I think the problem might be in the
backport itself rather than the USB substructure. I believe uCLinux would benefit
greatly from this effort. Any advice would be appreciated greatly please,
Thank-you very much
Daniel Djamaludin
