Have you checked to see if you have the serial port turned on in your 
bios? Have you tried to test the remote, with typing mode2 in a terminal 
to see if the remote is sending?
   If you are using the Huppauge receiver why not use the port on your 150?
I don't know where you are located,but may be you should buy the parts 
as listed on that site(the Huppauge may need different components to 
work) and get it working and then modify  it to suit your setup....
Not much help, but a few suggestions....
Good luck....
