It works pretty well for most of Linux hosts but when trying to register the webcam driver on Windows 7/8 I got "This device cannot start (Code 10)" message. I decided to try out the old version of the driver before the videobuf2 modifications and some other stuff (mostly the pretty initial driver) and it worked correctly on Windows 7/8. Has someone else experimented a similar issue? Is this a regression problem? I noticed that newer version of the patch need several tries to get the streaming working correctly on Linux hosts but I have been unable to get it working at all with Windows. Regards, -Marco
