I have a Microsoft LifeCam VX-3000. My desktop computer has two USB buses. 4 external ports on one bus in the back of the computer, and 2 external ports on another bus in the front. The webcam only works properly on the front-facing ports. I'm using the lastest stable release of the gspca_sonixj module.
The problems I experience is that the webcam is not able to work with Google's gchat video chatting. The screen remains black for a few seconds, before fading to gray. Sometimes I see myself for a split-second before it fades to gray permanently. The webcam always work fine with local programs like cheese. syslog output: webcam plugged into "bad" USB bus: Jul 24 22:09:22 Bluemoon kernel: [432235.451132] usb 1-1.3: new full speed USB device using ehci_hcd and address 10 Jul 24 22:09:22 Bluemoon kernel: [432235.562660] gspca-2.13.2: probing 045e:00f5 Jul 24 22:09:22 Bluemoon kernel: [432235.563467] sonixj-2.13.2: Sonix chip id: 11 Jul 24 22:09:22 Bluemoon kernel: [432235.564042] input: sonixj as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.3/input/input17 Jul 24 22:09:22 Bluemoon kernel: [432235.564178] gspca-2.13.2: video0 created Jul 24 22:09:22 Bluemoon rtkit-daemon[1365]: Successfully made thread 9824 of process 1506 (n/a) owned by '1000' RT at priority 5.
