girder wont see the usb-uirt

i havent used my usb-uirt for several months now and i am just gettign back into it. i fired up girder, the plugin is installed and enabled.
and if i go to a command and then click on the learn event button and then point my remote at the usb-uirt and press a button, girder does not see the IR. when i press the key on my remote, i see the red light on the usb-uirt flashing so i know it sees the ir, but for some reason girder isnt seeing it. any ideas please?
