MyGica D690

Mygica D690 [1] is a DMB-T/H USB stick targeting the Hong Kong, Macau and Mainland China market, supporting both multi-subcarrier and single-subcarrier modes. It contains a Realtek RTL2836B DMB-T/H Chipset and a ADMTV804 digital tuner IC. The dongle identifed as Vendor_id(VID)=1f4d and Product_id(PID)=689b. USB_VID_GTEK(VID) also is 1f4d.

I can't make this work as of December 2013. Nor can I find any support for it in the media build/kernel.
