However, when I run xawtv, I get these errors every few seconds: kernel: usb-uhci.c: interrupt, status 2, frame# 1575 kernel: *_comp parameters have gone AWOL (2/0/0/0) - reseting them The same errors were posted to the cpia list in May of last year, http://mailman.risc.uni-linz.ac.at/pipermail/cpia/2001-May/001056.html and wrt other topics occasionally on lkml. The origin of this error message is a patch for a color balance problem: http://mailman.risc.uni-linz.ac.at/pipermail/cpia/2000-March/000559.html This is the patch: http://mailman.risc.uni-linz.ac.at/pipermail/cpia/2000-March/000570.html The patch introduced the error message -- "By the way - I left a warning in place in the patch. If the patch is working correctly, then the warning should *never* be printed out." This warning is the one I'm seeing: + printk (KERN_WARNING "*_comp parameters have gone AWOL (%d/%d/%d/%d) - reseting them\n", It looks like this color balancing patch, introduced into the driver in March 2000 (cf. http://webcam.sourceforge.net), is not working and is generating an otherwise irrelevant error message to that effect. I'll leave it to Peter Pregler and the other cpia developers to determine whether the color balancing really is a problem or not -- I can't say I see one. But the error message is clearly unnecessary and should be removed. Cheers, Peter I compiled usb-uhci into the kernel, and run these modules: Module Size Used by cpia_usb 4800 0 (autoclean) (unused) cpia 50832 1 [cpia_usb] videodev 6176 2 [cpia] The device is an Ezonics EZCam and the picture looks great. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
