Thanks.  That helps.

That's fine for the defines that already exist.  But there's probably 
more work needed here.

Nice job.  And yes a picture in this case is worth 10000 words :-)

Uh, yeah.  That helps immensely.  Congratulations, the FX2 is already 
operating (the FX2 firmware is required for I2C transactions to work 
properly).  Assuming that you didn't first start the device from 
Windows, then yes it is able to load its FX2 firmware from its own local 
ROM.

The 0x51 device is very likely your local ROM (the FX2 has enough 
built-in smarts to bootstrap from a locally connected I2C ROM chip).

The 0x44 device I suspect to be your cx25840, but I'm a little puzzled 
as to why the driver couldn't initialize it correctly.

There's a lot more to be done.  Probably would be best to meet up on IRC 
and discuss this.  Unfortunately I'm pretty much unavailable for the 
next 7 days (heading out to a convention for my "other" hobby).  After 
that we can try to coordinate getting this device working (and I can 
also finally do a serious chase on the oops problem discussed last week, 
AND I can get the Gotview fix pushed up as well)...
