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.
