Trying to get my web cam to work under Linux.
When ran "xawtv -hwscan" get:
This is xawtv-/opt/Xawtv, running on Linux/i686 (2.6.21.5-smp)
Warning: Cannot allocate colormap entry for "lightgray"
looking for available devices
/dev/video0: OK [ -device /dev/video0 ]
type : v4l2
name : BT878 video (Hauppauge (bt878))
flags: overlay capture tuner
[My note: nothing about a web cam though]

When ran "dmesg | egrep -i cam" get:
sn9c102: V4L2 driver for SN9C1xx PC Camera Controllers v1:1.34
usb 2-2: SN9C105 PC Camera Controller detected (vid/pid 0x0C45:0x60FC)
[My note: 0c45 is manufacturer 60FC is product code for which there is no product, yet]
Presume to driver is SN9c105 and that the camera is on usb 2.

Ran lsmod and got:
compat_ioctl32 5248 2 sn9c102,bttv
videodev 29184 2 sn9c102,bttv
v4l2_common 18688 4 sn9c102,tuner,bttv,videodev
Only because I installed Hauppauge Win2000TV but note sn9c102

I have been lead to believe the sn9c102 controller is a parent of SN9C105.
I have my video0 set up but no video1 and other tests "seem" to suggest the proper controller is on board and available as a module. I am confusing V4L2 and this sn9c stuff and am not sure if I really have a loadable driver here. When I run xawtv I get a b&w screen with an explanation and can do nothing with it except exit it. It gives me this message:
This is xawtv-/opt/Xawtv, running on Linux/i686 (2.6.21.5-smp)
Warning: Cannot allocate colormap entry for "lightgray"

for which I need an explanation of teh error here and what/why DGA?
If someone can make sense of this, an explanation of where I am at and what to do next would be helpful.

Have xawtv installed and limping along, i.e. can get B&W Tv and motion but no sound. Can get ppm & jpeg shots of screen (this is what I use to start the motion on selected channel). Am not getting any errors now when I start xawtv.
SN9c102 is apparently the camera driver. I found the framegrabber addr in /var/log/Xorg.0.log using grep. Will try web cam when xawtv is fully resolved.
