The datasheet is missing too much important information needed to
write a fully featured driver for the part, and I wouldn't recommend
using a usbsnoop for this type of tuner, but be my guest and prove me

You might be able to get it working, but you'll end up with tons of
binary blobs hardcoded for each frequency, unless you use a
programming guide.  Unfortunately, I don't have one that I can share

I think you would be much better off purchasing supported hardware, instead.

Good luck, though...
