GrabBee-HD

[Dave Kimble <dave.kimble@riseup.net>]

I have just bought an HDMI to USB-2.0 grabber called "GrabBee-HD".

Inside it has chips labelled "Sigma PL330B-CPE3" and "iTE IT6604E".
Note that it compresses the video with H.264 .

I knew it probably wouldn't have drivers for Linux, but it does have 
Windows drivers on CD,
so since I run Ubuntu-VirtualBox-WinXP I thought it might well work one 
way or another.

On Ubuntu 14.04, the USB device is picked up:

but it is not recognised as a video capture device by VLC.
/dev/dvb/ , /dev/v4l/ , /dev/video0 do not exist.

So I fired up VB-WinXP and installed the Windows drivers and software, 
and restarted.
Then plugged in the device, which should connect the device to the 
driver, but it didn't.
Starting the Grabbee-HD software gives "No video capture device is 
connected!"
Then I realised the USB device has to be passed through the VB interface,
VB-Manager > USB > Add > "no devices available".

So because Ubuntu doesn't properly recognise the device, it can't pass 
it on to VB and XP.

Is there any chance of getting this going on Ubuntu 14.04 natively?
