USB-UIRT Forum

Hi guys,

I was playing with trydrv.exe from API sample package and I noticed
strange behavior with one of the remote controls.

trydrv.exe can learn the IR code for a certain keypress on a remote,
but it does not "see" it under a regular operation. In other words,
fn_UUIRTLearnIR returns the IR code, but IRReceiveCallback set via
fn_UUIRTSetReceiveCallback is not picking it up.

Does anyone know what is up with this ? The remote is a stock Shaw
Cable HD PVR one, and the key in question is Volume Up and Down.

Thanks,
Alex

(edit) Two other things -

* the frequency of for Volume Down is 57842 (give or take) vs 38458
of other buttons that _are_ getting picked up by IRReceiveCallback

* holding down Volume buttons sometimes completes the learning, but
in most cases the button needs to be pressed repeatedly (and rapidly)
for the learning to progress

Ah, it's right there on the front page

56KHz IR Receiver Add-On Option

So how would one go about getting this add-on option ?

Nevermind
