Every so often, I totally fluke it and running xawtv produces a perfect real
time image from my logitech quickam express.
ditto using Sane's scanimage
On most reboots however, using what I think are identical means of setting
the usb camera up, xawtv simply shows a black screen. no errors, nada.
I *think* the problem is either in the X server, or, in one of the higher
non-usb modules such as videodev. The usb component modules report no errors,
and indeed, using debugs and tracing, the video stream coming from the camera
seems 100% ok.
But, I'm lost chasing a paper trail trying to find why the image has gone
black when image data is indeed getting thru the usb driver subsystem.
I am reasonably certain the modules loaded and the paramaters, in fact
everything i do is identical, working and non-working. I *think* the problem
is order of loading or some sequence like that (eg starting usbcore too
early, whatever)
Is someone here on on the usb mailgroup or anywhere else, that has seen this
problem before?
