trouble setting up w/ Dish 301 in Sagetv 4.1, transmit only

The usb-uirt seemed to install ok, but I don't even know if it is working. When I get to the Sagetv source setup and it asks to press the 0 button until told to stop, nothing happens. I'm pointing my remote directly at the device. It is a uhf remote but I'm pretty sure it also sends out IR signals.
Any ideas at all are appreciated.
thanks.
