Can't get Girder Going...

Hi.
I received my usb-uirt yesterday. I install the driver, Girder and put the UIRT plugin in the plugins folder. What's next?
" Plugin is loaded in memory but hardware initialization failed."
I have tried all the options in the plugin dialog box with no luck.
If I install any other plugin like the Keyboard plugin, Girder functions properly.
Any ideas?
