Making it work

Linux kernel driver, enable CONFIG_VIDEO_USBTV: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/media/usb/usbtv

Change usbtv-core.c

Original code: 

static struct usb_device_id usbtv_id_table[] = {
	{ USB_DEVICE(0x1b71, 0x3002) },
	{}
};

New code: 

static struct usb_device_id usbtv_id_table[] = {
	{ USB_DEVICE(0x1b71, 0x3002) },
	{ USB_DEVICE(0x1f71, 0x3301) },
	{}
};

Make & install.

Check

udevadm monitor

Plug in device.
