For someone to add support to a device, it needs to have that device (or
a similar one), and to be able to get access to the datasheets or to use
some reverse engineering technique. One important information is what
are the chips inside the device.

Take a look at linuxtv WIKI pages. It explains several useful things
on how to add support to a new device.

The USB ID used by your device is generic: all devices with em2870 without
eeprom will inform the same code (and even some with eeprom, but where
the vendor didn't care to write their own ID there).

What are the components used on your device?
