Hi,
I hope I'm on the correct list for gspca driver development. By
searching I came up to the old driver page and the gspca project
page http://linuxtv.org/hg/~jfrancois/gspca/
I recently bought a nice new webcam without Linux support (that was not
very important for me as I have a working webcam already but this one
has several useful features especially at work where I often don't or
can't use Linux unfortunately). The webcam is called VAD (Vicious and
Divine) Laplace from the manufacturer Speed Link.
So I thought helping to get a driver for this cam. What I can offer is
USB sniffing on a certain OS (no MAC drivers available too so there is
not much choice). I already know that the cam is not UVC compliant.
I have searched for some more hardware information than from the vendor
available but in vain (though the cam is about 1 year old already).
I know that especially the video format the webcam delivers would be
important to know for driver development.
If there are any (freeware) tools available except those USB sniffers to
find out any more hardware details please let me know, so I can help
with the driver.
The basic hardware SPECS are below and I attached USB HW information
from /proc/bus/usb/devices (with lsusb). IDs are idVendor=1ae7,
idProduct=9003 (9004 is the other variant of the webcam in black).
- 2 MP Photo, 1.3 MP Video resolution, USB 2.0 (1.1 supported)
- 3x digital zoom, Flash, Night illumination (3 hardware buttons)
- Noise-suppressing microphone, Mute button
- Z-fold positioning, 0.6m cable CAM, 1.4m extra USB extension cable
- max. resolution 1280x960/15fps, 640x480/30fps, photo 1600x1200
Sorry, it's not really much I found out so far. But I hope that I can
be of further help for driver work. I intend to do some further tests.
I think it's most appropriate to post results on the linuxtv wiki, so
I created a new page there:
