Has anyone replied to your actual question yet?  I have a D12-300 (not 
sure how similar it is to the D11-500) with a USB port on the back.  I 
used one of my old pl2303 cables that I bought on eBay a few years ago 
and it works perfectly.  I used the directv3.pl script from the pdp8 
site mentioned.  I call the script with:

/usr/local/bin/directv3.pl box_type d10-100

No other options were needed because on my myth box I am using 
/dev/ttyS0.  If you are using a different serial port you can use: 
directv3.pl box_type d10-100 port /dev/ttyUSB0' for example.  I did use 
a null modem cable between the directv receiver and the myth box.
