What is the output of "dmesg | grep si2168" from your last boot?

I know I tried with various (and no) firmwares when I was getting it to 
work and not all of them had it as an HD tuner as well as SD.  I get:

[   47.737489] si2168 3-0064: Silicon Labs Si2168-B40 successfully

If it's using something other than b40 try deleting it and see if it 
works again (or just delete all the ones other than the two I mentioned).

After that delete all tuners (not just all on host) and do a scan of all 
channels in mythsetup and see if it picks up HD.

The main issue I have with it is I can't remove it from the USB port 
without freezing the computer so the support isn't perfect...!  But they 
seem fine just leaving them alone.
