Worked it out!
Just in case anyone has same problem, the device template had lost the setting for which device/port was controlling it.
In this case the USB port had somehow changed from pci0000:00/0000:00:02.0+2 to pci0000:00/0000:00:02.0+3
Therefor opened the device and changed the COM port to the correct port that the USB UIRT was running on, and voilla can now learn codes again.
Can you please explain how to find out which port the device is connected to?
I am sorry , this might sound silly but I got my new USB uirt but unable to get it working.
I think I am missing some step to set it up and configure it.
I had my uirt pnp and the system installed its software successfully. followed by when I see under my devices ---> Media director i see windows XP MC remote is installed and Infrared Receiver is set to USB UIRT 0038.
MY USB uirt Device is #36.
My questions are....
1. I do not use windows remote, do I need that windows remote installed as remote.
2. I use logitech dinovo mini. so basically I need
logitech---->core/system------>usb-uirt--------->sony TV
is it possible ?
Please help me here.
Thanks.
