Warm state ... no firmware download required (well, not right now
anyway).

Oh well, I was just hoping your device would have the same
tuner/demodulator config as one of the supported devices. Since it
evidently does not, you will need to do some work to find out
what it does have. Are you able to open it up and find out
what chips are inside?

Time to stop playing now I think. Next step is to open it up and look
what chips it uses, and/or do lots of windows usb traces to find the
i2c bus addresses of those chips.

I couldn't download this; it is wrapped in HTML.

It's part of the device configuration struct in m920x.c, but when you
plugged in the device (as you showed above) it was in warm state, so no
firmware was required to download.

You should try to extract your device's firmware from that dvbsnoop
output so you won't be dependent on Windows when you get the device
working.
