Dev file /dev/video0 is created however the apps have trouble showing
anything (skype has some random color lines,camorama outputs error ).

In 8.04 there was some other driver used (just gspca, also source was
different from the 8.10 one), so if it was rewritten, there is maybe
some bug in it.

I have also tried to bould it from the latest sources from v4l, but i got the same :
[79342.851778] gspca: main v2.4.0 registered                                                                                                                                 
[79342.854980] gspca: probing 046d:092f                                                                                                                                      
[79342.918474] gspca: probe ok                                                                                                                                               
[79342.918522] usbcore: registered new interface driver spca561                                                                                                              
[79342.918569] spca561: registered                                      

and the output in apps was exactly same as with the previous gspca v2.2.0.
                         
On 8.04 , the driver used is (which works correctly) :
[   90.414348] usb 3-1: new full speed USB device using uhci_hcd and address 2
[   90.522730] usb 3-1: configuration #1 chosen from 1 choice
