[linux-dvb] Sumvision T680 usb dvb stick (0572:6813)

Hello,
I guess these are new to the dvb-usb scene, since a google search for
"Sumvision T680 linux" brings up very few (and all unrelated to linux
dvb) results.

I have bought a Sumvision T680 usb stick. It was cheap (£20). It does
not work in Linux. I modprobed every dvb-usb module (that is currently
in stock ubuntu 7.04), none of which claimed it.

I made a brief search through recent mailing list posts and the latest
v4l-dvb source tree, which found nothing interesting or apparently
relevant.

Vendor/product Id is 0572:6813.

How do I go about figuring out if this is something else rebadged or
anything like that?

Product webpage is
http://www.sumvision.com.cn/results_pages.asp?product_type=22#1999

You can buy it in the UK from svp: http://svp.co.uk/products-solo.php?pid=1492

lsusb output below sig; any help is appreciated...

Greg.
