Laurent, I just tested your patch with the SVN 205 and its able to recover. I tried with luvcview and Skype with the same results.
I recompiled without the printk ;) but I noticed that as soon as plug my webcam and the uvcvideo driver is loaded the performance of my laptop is going down down down. In a couple words is running slower. Any idea why? This is what I got from dmesg: [40979.612000] usb 1-1: new full speed USB device using uhci_hcd and address 4 [40979.980000] usb 1-1: configuration #1 chosen from 1 choice [40980.904000] Linux video capture interface: v2.00 [40981.176000] uvcvideo: Found UVC 1.00 device <unnamed> (046d:09c1) [40981.196000] input: UVC Camera (046d:09c1) as /class/input/input13 [40981.196000] usbcore: registered new interface driver uvcvideo [40981.196000] USB Video Class driver (SVN r205) [41198.716000] uvcvideo: Non-zero status (-84) in video completion handler, retrying.
