Is cheap (U$S 35 here) 3. Is listed as supported on the Gspca/Spca5xx, Spca5xx-LE WebCams Driver Compatibility Chart Is marked in Support column with Yes in green, and 3 stars... Now I see why 3 and no more, it have some video quality problems that I will describe in this post. Before describing the problem, I must tell that is the 3rd day searching the web for a solution and no luck. Only a thread in a Ubuntu forum with no solution. Also I can't find a Bug Report area for the gspca drivers. This is the scenario an the problem: My hardware Processor: Pentim 4 1.8Ghz USB version: 2.0 Webcam: Microsoft VX-3000 (LifeCam) lsusb: Code: Bus 003 Device 003: ID 046d:c517 Logitech, Inc.

When started, it uses the small format, and video is very dark, colors distorted (see attachment gqcam Half Size) Seems that nothing I do with controls help to get my face visible. Something happens allways, in gccam and the other programs I've tested... When touching any paramenter (brightness, hue, etc), contrast is reset to a fixed level, then when touching contrast control is goes to the set position). In half size same kind of problems. In full size the image is accepable, but same problem with contrast control. This is the only program and format with I can get a decent video output. Skype In Options - Video Devices I've a Test button. Similar to half quality but seeing only a portion of the sensor capture surface. In a video call, sending video looks similar, but after a few seconds the image starts scaling, camera led blinks almost 5 times and at the end video seems to be ok: I can see myself almost gqcam in full size, but the other person only see a distorted frozen picture of me vertically inverted. Kopete Going to Settings -> Devices -> Video I see video output exaclty like gqcam half size, and controls react with the same problem touching contrast. wxcam The program starts in aparently in 320x240, image is visible, I can see my face. Gradually in 10 seconds it gets dark like the previous half size example. After going to Settings -> Preferences application crash, I've started from console so here is the output: Code: me@pc~> wxcam Cannot open input file: No existe el fichero o el directorio Resolution setted to 320x240 Determining video4linux API version... /dev/video0 is no V4L2 device Using video4linux 1 API Determining palette format...

Touching Settings -> Picture functions I can't get my face visible. Now going to Settings -> Frame options, I select 640x480 and again same image quality as same size in gqcam, the only mode with an acceptable video output. Here going to Picture Functions again, I can adjust the image correctly, but the same "Contrast reset" as described in other applications. camorama Starts ok, first video output is dark, like half size in gqcam. Nothing to do with image Adjustments to correct it. In this mode seems that constrast reset don't happens. White Balance have no effect, I forgot to mention that either have no effect in other apps, in any size. If I select View -> Large application crash, for a instant seem to show the large video output before crashing. This is the console output: Code: me@pc:~> camorama (camorama:3140): Gtk-CRITICAL **: gtk_entry_set_text: assertion `text != NULL' failed name = medium name = large me@pc:~> Same crash selecting View -> Small, but console output ends in "name = small" Of course the desired result is that the driver works fine in all applications, most in IM clients like kopete and skype. I hope this thread could lead to that. Conclusion If someone can share it's experience in order to try to solve this problem I can run necesary tests and submit the results here. Also if someone know where to report the bugs of gspca controller I'll do it.
