=== 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 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.

Note: This seems to only enable the device to capture AV, not to do TV or FM reception.

For example start ''tvtime'' :

''
tvtime -d /dev/video0 -x /dev/snd/controlC1
''

NOTE: As said, only AV capture seems to work, so tvtime will only produce errors, not image.

===Remote Control Support===
The device comes with a small remote control. Linux support is unknown.

===Drivers and software===
The devices comes with a mini CD containing WinXP to Win7 software with BlazeVideo HDTV Player v6.0.<br>
It also includes a small remote control, an antenna and a cable to connect to some AV device for capturing.

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.

Note: This seems to only enable the device to capture AV, not to do TV or FM reception.
