Right, no serial ports on the motherboard, hence the need for a USB to
serial cable for the Linux side. This will take a USB port on the Linux
computer and make it an RS232 port so you can use a USB to serial
adapter on the DirecTV side and use a DB9 to DB9 null modem cable
between the two USB adapters. As for your next question; No, there is
no direct USB to USB cable that can be used between the Linux and
The USB-serial on the Linux side isn't too picky as Linux supports most
adapters. The USB-serial on the DirecTV is extremely picky and you have
to use a pl2303 adapter (which have been discontinued, but you may still
find some out there).
