[Qce-ga-devel] Dexxa 046D:0870 ?

[Ronojoy A. <rj...@ph...>]

Hi:

I am trying to get a webcam with the following numbers on its label
	P/N: 861050-1010 (note that its not 00xx!)
	S/N: LZA11434320 
to work on a SuSE-7.3 installation (kernel 2.4.10-4GB). The device is
listed on the usb bus as: Bus 001 Device 003: ID 046d:0870 Logitech Inc.

First question: the product id seems to indicate that its a Dexxa webcam,
but the P/N points to a Quickcam Express - except that the 1010 seems
nonstandard. Any ideas as to what this webcam really is, and what the
correct drivers to be used are ?

Anyway, assuming it to be a Dexxa I tried the drivers of Jonas Munsin, but
they either hang my machine (xawtv) or produce errors (gnomemeeting).

So I went on to try the qce-ga drivers. On insmoding the qce-ga-0.40c
driver the kernel says
	Linux video capture interface: v1.00
	usb.c: registered new driver quickcam
	USB Quickcam Class ff SubClass ff idVendor 46d idProduct 870
	USB Quickcam camera found using: $Id: quickcam.c,v 1.102 2002/03/25 
	22:22:34 jfclere Exp $
	quickcam: probe of HDCS1000 sensor = 08 01 id: 08
	quickcam: HDCS1000 sensor detected
and the modules are listed as well (usb is alread running)
	mod_quickcam           39616   0  (unused)
	videodev                4544   1  [mod_quickcam]
All fine till here. But now the problems:

(1) motv or kwintv do not see the webcam 
	motv -noscale
	This is motv-3.72, running on Linux/i686 (2.4.10-4GB)	
	Warning: Actions not found: Remote
	Warning: Actions not found: Remote
	WARNING: no plugins found [/usr/X11R6/lib/xawtv]
	/dev/video0 [v4l]: no overlay support
	v4l-conf had some trouble, trying to continue anyway
	no video grabber device available
though xawtv does, but with error messages:
	xawtv -noscale
	This is xawtv-3.61, running on Linux/i686 (2.4.10-4GB)
	/dev/video0 [v4l]: no overlay support
	v4l-conf had some trouble, trying to continue anyway 
The fps and quality isn't too good, and there is a fuzzy band at the
bottom of the window. Further, any rapid movement of the window freezes
the cam output with an error message:
	ioctl: VIDIOCSYNC(0): Input/output error
	ioctl: VIDIOCSYNC(1): Input/output error

(2) If I start up xawtv again, it segfaults, or produces the message:
	This is xawtv-3.61, running on Linux/i686 (2.4.10-4GB)
	can't open /dev/video0: Device or resource busy
	v4l-conf had some trouble, trying to continue anyway
	v4l2: open /dev/video0: Device or resource busy
	v4l: open /dev/video0: Device or resource busy
	no video grabber device available
but, surprisingly, gnomemeeting works fine - well almost, because it
manages to show the images from the webcam, but with the standard
warning "cannot open /dev/vide0...a test images will be displayed".


Any ideas on how to fix the behaviour in (1) and what is going on in
(2) ? Thanks in advance,

Ronojoy.
