confirmed it doesn't show in latest svn
(previously I tested 0.9.7 ubuntu build)

I'll try too look at libv4l support later

this appear to be fixed too.

yes now the camera name appears correctly (I believe)

it says: UVC_Camera_[04f2:b172]
in fact driver in use is uvcvideo

$ lsusb -d 04f2:b172
Bus 001 Device 003: ID 04f2:b172 Chicony Electronics Co., Ltd 



now I get a different type of error:

camera supports palettes : 8
error: 
ioctl VIDIOCSCHAN: Invalid argument

(when I open the camera device)

but I'm unable to get any frames out of it. here's the error when I bang
#camera:

error: 
ioctl VIDIOCGMBUF: Invalid argument
error: 
[#io.videodev in /dev/video0]: ioctl error
... you might be able to track this down from the Find menu.
