The device advertises a maximum resolution of 720x480 in the UVC descriptors it exposes to the host, so there's nothing the driver can really do to obtain 720x576. If plugging an active PAL source to the device before plugging it to the USB port doesn't help, another option for investigation is to capture USB traffic under Windows to check what happens there. -- Regards, Laurent Pinchart
