The PC expects to be a usb host if you plug a USB device into it. a
Usb->serial adapter will only look like a usb device on the usb side -
the serial side will look like nothing but a serial cable. If the cable box
is
designed to be the usb host and will take incoming commands from a
usb->serial
adapter, it sounds like it will work (I will be trying the same thing on my
satellite
STB once I get my usb->serial adapter in the mail).

That would be ideal, and would certainly be an inexpensive option. The

yeah, if the port converter works, that's def the way to go. It's around $9
or $10 for
one of those converters if you shop around online.
