There was a bug in the previous version: the frames lack a JPEG header.
It is fixed in the new version 0.0.24.

I have no 307b camera, but you may send me information for I make
it work. First, try the last version with the small program I sent
this morning (grab.c). The file it creates (toto.jpg) should be
displayed by any graphical program (evince, dillo, firefox...).
If the picture is correct, the driver should work with any client
understanding JPEG frames such as luvcview, and it should work
too with the help of 'jpegdec' for v4l1 clients as Skype or vlc.
If the picture is not clear, send me the file for I have a look.

The other possibility is that you cannot get a picture (grab stays
hung). In this case, activate the debug trace by:
	echo 0x3f > /sys/module/gspca_main/parameters/debug
Then, plug the camera, do the grab and send me the kernel trace.
