Comment 11 for bug 172678

I have discovered a "dirty fix" conserning this bug. It appears to be connected to a physical connectivity problem with the rotating Acer OrbiCam attached to my Acer Aspire 5684WLMi.

During Linux loading, when the computer repeats "... gspca_core.c: Failed to configure camera" without stopping, I press the camera gently from pointing at me to pointing upwards, maybe 15 degrees. When I reach this spot, gspca stops complaining, and Linux loading continues, and I can stop pressing the camera (and the camera works).

I don't know if this dirty fix only applies to my (maybe badly connected) camera, but it can be worth a try. I have to do this (almost) every time I boot up my Ubuntu laptop (sometimes it loads without problems, and maybe several times in a row if I don't touch the camera in between). And, off course, I take no responsibility if you damage your camera/laptop while trying this dirty fix, you do this at your own risk.

If you don't need the webcam and don't want to wait for a bugfix, you can simply blacklist gspca. If you are using the webcam you can try to use this dirty fix.

I have included the dmesg log before and after I do the "dirty fix". As you can see, before my "fix" the USB device appears to disconnect before gspca has loaded the driver.
