View Full Version : [all variants] i-tec icam tracer webcam and ubuntu/linux

December 27th, 2009, 02:44 AM
Hi everyone!

Me and a lot of astronomers use these days the webcam model "i-tec icam tracer" to record movies from the planets and then by choosing the best pictures and stacking these, we create quite high resolution images.

As far as I know, actually nobody got it to work (uvc, v4l, pwc) with linux - neither with ubuntu nor any other linux distribution :(

"lsusb" delivers
Bus 001 Device 004: ID 2770:930b NHJ, Ltd CCD Webcam(PC370R)

Here is a link to a driver project http://gkall.hobby.nl/sq930x.html - I was not able to achieve any advancement.

Is there a genius spirit out there who could help me/us?

My thanks in advance,

Habe das selbe Problem.
Ein weiterer Thread ist bei:

mit (PC370R) bei lsusb melden sich die Kameras
"NHJ, Ltd CCD Webcam(PC370R)"
der Vertriebsmarken
- "i-tec, iCam Tracer CCD"
- "Network CAM 4300"
oder eine weitere mit demseben code aber anderem Namen:
"ORite ORITE USB 2.0 CCD Webcam(PC370R)"
(weitere sind mir nicht bekannt)

Meine Treibersuche verlief ebenfalls negativ.
Habe die Kamera mal zerlegt und versuche die Fotos hier reinzustellen; man kann die Beschriftung der Chips erkennen. Wäre nützlich, wenn man einen Kontakt zu der Firma, die die Treiber geschrieben hat finden könnte.

... Ergänzung:

Die Chipbezeichnungen sind auf dem Foto nicht perfekt erkennbar, hier nochmal:
- Sony, D1267AN, 20 Pin SO-Wide Gehäuse
- AD, 9943KCPZ, 32 Pin Q... Gehäuse
- SQ, SQ930B-L

Hello, After exchanging some e-mails with the linux gspca maintainer. the cam seems now to work somewhat. Although the driver is not ready and still in development.

You can download the gspca_test tarball here:

It would be good if there are other testers who can help the gspca maintainer to complete the driver for that cam.

It may also help, if there are people who use this cam in windows. To develop a linux driver, USB traces are interesting. Install a free usb sniffer http://benoit.papillault.free.fr/usbsnoop/ and set it up for the webcam, then connect the webcam and take some images and / or change some settings of the driver. This gives helpful information of how the pc must communicate to the cam.

Hopefully, we will soon have a good linux driver for this interesting and light sensitive webcam.

Itec icam tracer working (?)with gspca - sq930x driver but i cannot set the fps. Cheese shows the image inverted but colors are ok. With guvcview we can hange gain and exposure values, size (320x240 or 640x480) but cannot set I420 compression nor fps values, asigned by default to 1fps (too low for capturing palnetary images!)

but this works finally. White balance and fps is needed for astronomical use of this cam, so if anybody knows the trick...

ok, i tried v4l2ucp with cheese and all is ok. I have more fps ( exposure value limits fps, thats correct, but now i can take decent video captures )
