That means nothing happened when plugging the stick in?

How did you check the chips that are present?
Did you read through the inf file of the windows driver or open the device?
Looking at the inf file you attached, it most likely has a si2165
dvb-c/t demod.
I wrote a first driver for this demod.
But I think the tuner is unsupported (si2173 or si2170 as inf file says).
Google only found these documents:
- https://www.silabs.com/Support%20Documents/TechnicalDocs/Si2173-short.pdf
- http://electronix.ru/forum/index.php?act=attach&type=post&id=66442
But both documents skip the detailed programming.
And I found this driver for si2176:
https://github.com/fards/AMlogic_Meson6_030812release/blob/master/drivers/amlogic/tuners/si2176_func.c
But I am not sure about the relation between si2170, si2173 and si2176
For adding support your device, you need to go through the normal
process described in the wiki.
Part of this is recording usb traffic.
This can then partially be matched to the existing drivers.
