I bought this nice looking webcam for only $13.68 with free shipping included on dealextreme.
http://www.dealextreme.com/details.dx/sku.12939~r.28238939 At first I couldn't get it to work. It gave the errors : Failed to query (135) and Failed to query (130) But I got it to work by setting quirks=2 Now it works. Tested with VLC and Ekiga. With luvcview it still gives a black window or an all green one with buttons at the bottom. ===== WITHOUT QUIRKS=2 ===== [165424.597040] usbcore: deregistering interface driver uvcvideo [165450.191502] Linux video capture interface: v2.00 [165450.228734] uvcvideo: Adding mapping Brightness to control 00000000-0000-0000-0000-000000000101/2.
