Comment 20 for bug 255678

I have the same problem: in Jaunty the Creative PC-CAM 600 webcam does not work anymore. This is a fresh Jaunty installation. The webcam was working in a previous release such Feisty so the bug is a regression.

At each connect I get this message:

abramo kernel: [ 3031.407320] usb 2-1: USB disconnect, address 9
abramo kernel: [ 3042.244054] usb 2-1: new full speed USB device using ohci_hcd and address 10

abramo kernel: [ 3043.588921] gspca: probing 041e:400b
abramo kernel: [ 3044.033373] gspca: disconnect complete

I need to reload the gspca_sunplus module manully each time I connect the webcam:

sudo modprobe -r gspca_sunplus
sudo modprobe gspca_sunplus

in order to have the correct creation of /dev/video0. The log message while unloading/reloading the module is:

abramo kernel: [ 3140.197307] usbcore: deregistering interface driver sunplus
abramo kernel: [ 3140.204126] sunplus: deregistered

After the module reloading the webcam works well with Cheese and xawtv. However with skype and ekiga the image quality in very poor (dark) at a level that I can hardly distinguish any shape.

I'll be happy to provide any further information.
