Just wondering if you can use libusb-1.0 for the user space still image functionality. libusb-1.0 offers the following functions to do that for you under Linux. int libusb_kernel_driver_active (libusb_device_handle *dev, int interface) Determine if a kernel driver is active on an interface. int libusb_detach_kernel_driver (libusb_device_handle *dev, int interface) Detach a kernel driver from an interface. int libusb_attach_kernel_driver (libusb_device_handle *dev, int interface) Re-attach an interface's kernel driver, which was previously detached using libusb_detach_kernel_driver(). So you can detach the kernel v4l2 driver at the beginning and later re-attach it when you finish. -- Xiaofan -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
