Hi Adrian & Laurent, This sounds very similar to the problems I've been having with my camera (Subject: [Linux-uvc-devel] New camera not yet supported. (1871:0306))
In my case once the camera is running it remains stable unless I unplug it. I'm convinced the issues I'm having are not with the driver but are at a more basic USB level. When it plays up a "lsub -v " hangs at various points for several seconds and produces errors that various points didn't respond. I've tried the very latest kernel without success. It occasionally errors and completely unloads the USB2.0 system The next thing I'm going to try is to do a forced reset of the device and see if that helps. I'll post my results.
