The fwfind script makes a lot of assumptions about your environment.  If 
you can't get that to work, you can always fall back to running 
fwextract.pl directly.  See the web driver page(s) for more info.

Look for tveeprom.ko - the symbol is defined there.  See if you have it 
loaded, and if not make sure it gets loaded.  Without that module, the 
device's prom can't be read and without the prom data, the driver will be 
unable to select the proper tuner type, which will make the driver mostly 
useless.

The indirect method does not directly call tveeprom_hauppauge_analog, but 
instead issues what basically amounts to an ioctl through the I2C code to 
indirectly ask the driver (tveeprom in this case) to do its job.  However 
if tveeprom isn't there (which the missing symbol would suggest), then 
there's no way this will work either.

This is an unrelated issue.  The driver doesn't implement all the 
ioctl()'s it probably could.  However the missing ones are not fatal; the 
driver will still work correctly.  So don't worry about this.

The root cause problem is tveeprom.ko.  Make sure you have that module 
loaded.  Either use the one that's already part of your kernel, or copy in 
the ivtv version.
