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.

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.
It also includes a small remote control, an antenna and a cable to connect to some AV device for capturing.
