Well that's still correct but the shakeup was a while ago so the LIRC 
side might be caught up by now.  I hope...

Yes.  There's nothing else AFAIK to be done on the pvrusb2 size.

With HVR-1950 you have one other wrinkle to deal with.  The IR chip in 
this device is also the IR transmitter.  I don't know of anyone who has 
gotten the transmit side to work.  Again, this is outside the realm of 
the pvrusb2 driver itself - I just make the chip accessible.  Last I 
heard about this (and the information is WAY old by now), there was 
support in LIRC for the IR chip that the HVR-1950 uses however 
apparently the chip needs firmware loaded (by the corresponding driver) 
and that the particular firmware needed in the HVR-1950 "environment" 
does not match what the LIRC driver is trying to load.

Anyone reading this please post corrections to that summary if you have 
more recent info.
